{{Under Construction}}The '''Azure Eye system,''' also known by the anthropic exonym '''13 Camelopardalis''', is a star system located approximately 424 light-years away from the Sun in the constellation of Camelopardalis notable for its dynamically packed system of planets.

Azure Eye is a single star system surrounding an A4V main sequence star, officially named '''Azure Eye'''. The star lies on the Delta Scuti instability strip, causing it to change brightness by 0.04 magnitudes due to helium opacity oscillation with a period of approximately two hours and thirty minutes. It also exhibits Alpha2 Canum Venaticorum variable behaviour, rotating on its axis every twelve hours and thirty minutes - thus, due to slight inhomogeneities in its visible surface, Azure Eye's brightness is also modulated at this period by an amount equal to 0.01 magnitude. This short rotation also causes the star's equator to bulge; its equator is measured at 12.6% wider than its poles. Azure Eye is highly enriched in the elements strontium, chromium and europium, with lesser overabundances in silicon, copper, xenon, phosphorous, manganese, yttrium and platinum, classifying it as a chemically peculiar Ap star; its planets are observed to exhibit similar abundance patterns.

Azure Eye's planetary system is divided into "circles", analogous to Sol's inner and outer planets. From inward to outward, they are:

*the Inner Circle, comprising of the system's "hot saturn" and several resonant planets orbiting outward from it; inclined to the mean system plane by 8 degrees,
*the Green Circle, centered on the water habitable zone but both extends inward to Nergal and outwards to the system's warm belt,
*the Resonant Circle, four large gas giants in a 1:2:4:8 orbital resonance chain,
*the Outer Circle, defined as the Kuiper-like debris disk maintained by Victoria and beyond

Azure Eye is also home to several spacefaring civilizations currently united under a single supranational organization known as the Azure Eye Confederacy.
==Composition==
Azure Eye is by far the dominant body in the 13 Cam system, making up 98.85% of all mass in its system. In some aspects, it is comparable to the Solar System - it has several rocky inner planets close to or just inside the habitable zone, a warm debris belt, four large gas giants and a cold debris disk. However, Azure Eye also possesses a system of close-in, resonant planets not unlike many star systems discovered in the early 21st century by the Kepler space telescope, maintained by two nearby warm gas giants. In addition, a large "puffy planet" orbits Azure Eye closely with a period of 9.982 days. A Saturn-sized gas giant also bookends the system in an extremely wide orbit with a semimajor axis of 284.43 ± 0.51 AU.
==Orbits==
All planets in the system orbit Azure Eye on nearly circular or mildly eccentric orbits, with the exception of EMONGA-2060-BLG-L1714, which is believed to have been captured in the star's birth cluster due to its extremely eccentric and distant orbit along with slightly different isotopic ratios. These orbits, with the exception of the Inner Circle, are all aligned to a common plane, due to the planets having formed out of a circumstellar disk in this plane.

The Inner Circle's orbits are slanted on approximately an 8-degree angle to the system's ecliptic (arbitrarily defined as the star's equator). The cause is likely attributable to Uncia, which is by a significant margin the largest planet in this region possessing this tilt; further supporting this is the simultaneous precession of the orbits all 5 of the Inner Circle's planets at a rate similar to that calculated for Uncia in isolation.

=== Uncia ===
'''Uncia''' is Azure Eye's first planet, with a mass approximately one third that of Jupiter. However, its radius is increased to greater than Jupiter's by extreme irradiation from its host star. It orbits extremely close to its star, completing one orbit in just under ten days.

The planet's proximity to its star results in extreme weather patterns, dominated by a pair of vortices somewhat east of the substellar point that dominate the planet's disk. Much of the planet is covered in clouds of forsterite (Mg2SiO4), save for these vortices, which are clear down to the deep TiVO haze layer, giving them a deep blue colour from Rayleigh scattering.

Uncia's exosphere is not gravitationally bound; it is losing an estimated 100,000 tons of hydrogen and helium per second, creating a large, diffuse gas tail extending approximately 40,000,000 kilometers in its wake.

Despite its proximity to Azure Eye, the planet nonetheless maintains one stable major moon similar to Io, dubbed Snep after a colloquial nickname for the snow leopard. Also like Io, Snep boosts Uncia's magnetosphere significantly, permitting the formation of a plasma torus which can be detected when Uncia transits Azure Eye.

=== Ailurus ===
'''Ailurus''' is a large, iron-rich "super-earth", with a radius of 1.64 earth radii and a mass of 5.45 earth masses. It has an atmosphere with a datum pressure approximately 116 times the pressure of Earth's surface, composed primarily of supercritical carbon dioxide, nitrogen and sulfur dioxide. A tidally locked planet, Ailurus' near side always faces its host star, driving it to stupendous temperatures of nearly 2,000 K. This heat is enough to melt Ailurus' crust, creating a lava ocean on its near side. The edges of this lava ocean host exotic, mineral-based life, and the planet's terminator is dominated by silicon-based organisms believed to have been seeded from Momonga.

Ailurus has three moons; two are small asteroids, the fourth is approximately 44% the diameter of Earth's moon. Ailurus also possesses a hydrogen-rich exosphere produced by the continuing decomposition of water in its atmosphere. Minerals occasionally precipitate out on the planet's night side, acting as the planet's primary economic source of hydrogen due to their water content.

=== Momonga ===
Momonga is a rocky terrestrial planet of approximately 1.15 earth masses. It has a thick atmosphere which exerts a pressure on the planet's surface equal to about 94 bar. Its atmosphere primarily consists of carbon dioxide and nitrogen, with smaller amounts of sulfur dioxide, acetylene, hydrogen sulfide, ethane and argon along with traces of other hydrocarbons. This reducing atmosphere allows the growth of exotic life. Momonga's near side is, like Ailurus, heated to extreme temperatures by its star, reaching 1,400 K at its substellar point. However, since there is less incoming stellar flux, Momonga has a smaller lava sea; a larger area is thus freed for land life and lakes of molten alkali salts. The planet's atmosphere is yellowish by scattered light and bluish by transmitted light, owing to sodium vapour in its atmosphere. Also generated by atmospheric sodium are the Momongan Crowns, which are energetic aurorae which are bright enough to illuminate portions of the planet's night side.

Life on Momonga utilizes the planet's salt oceans, mostly comprised of sodium sulfate and sodium chloride, as an ionic solvent. Skins of refractory ceramics ward off Azure Eye's brutal stellar flux and cross-spectrum UV radiation in "animals", while "plants" photosynthesize with charge transfer between icosatungsten pentacontaoctoxide (known locally as "gvtst") and internal pseudo-proteins. (wip)

Momonga has three small moons locked in a Laplace resonance, with diameters of 164, 115 and 244 km, respectively.

=== Quokka ===
Quokka is a small, roughly Mars-sized terrestrial planet with only a thin (log Patm = -5) atmosphere of relatively heavy gases, mostly xenon. Due to this lack of a substantial atmosphere, its surface is pitted with tens of thousands of impact craters. Tidally locked, Quokka's substellar point reaches 600 degrees Celsius; it glows a faint red when shadowed. The heat causes the rock in this area to soften, flowing at approximately a centimeter per year and erasing craters. Nonetheless, relief in this area persists for unknown reasons, possibly due to blocks of lower-density, stiffer rock rising through solid-state convection. Surprisingly, life - believed to have been transported from Momonga via panspermia - ekes out a tenacious existence on Quokka's surface, forming mats of microbial life on the surface.

=== Mijumaru ===
Mijumaru is a sub-earth with a mass approximately 0.7 times that of Earth. It has an extremely thick atmosphere with a surface pressure of over 300 bar at datum, composed mainly of carbon dioxide and water vapour. Both are potent greenhouse gases; nearly all incoming radiation is trapped and forced back onto the surface. At over 1,500 degrees, the heat here makes Mijumaru the second-hottest planet of the system and causes its surface to break down entirely into a slurry of metal-rich magma with bergs of periclase. The planet is still actively losing water via photodissociation and may end up similar to Venus if it cools down enough. Some regions of Mijumaru's clouds are tinted forest-green by particles of chromite carried up from its surface.

=== Nergal ===
Nergal is a gas giant with a mass of about 83 times that of Earth. From space, it is a dull magenta color from a combination of Rayleigh scattering, absorption from methane and a deep layer of sulfide clouds.

Nergal only has sixteen moons despite its large mass. This is believed to be because of Laz, its largest moon which orbits on an inclined, retrograde orbit. It is believed to have been captured, which would have led to a collisional cascade between Nergal's original set of inner moons which later re-accreted to form today's satellite system. In contrast, Nergal ((number)) is a solid body in a wide, inclined orbit, which may have been perturbed by Laz until it arrived in its current orbit due to stellar tides. Two additional minor moons orbit on wide orbits suggesting they were captured. Nergal is also notable for the presence of a large quasi-satellite about the size of Ceres.

==== Laz ====
Laz is by far Nergal's largest moon, at nearly a quarter Earth's mass and two thirds its radius. It is primarily composed of silicates, with an above-average-size iron core. Laz is an uncommon example of an Io-like volcanic world with an active biosphere, utilizing elemental sulfur as a liquid medium and dimethyl sulfone as an energy source, constructed from methane and sulfur dioxide in its atmosphere. Producers on Laz range in colour from light blue to indigo, utilizing the thiozonide anion, to best reflect the large amount of incoming ultraviolet light while taking advantage of the abundant energy, though some primitive plants are light red. Laz's atmosphere is violet due to disulfur and trisulfur gas in its upper stratosphere.

Azure Eye system

2025-02-07T02:55:48Z

Sogga: /* Momonga */

{{Under Construction}}The '''Azure Eye system,''' also known by the anthropic exonym '''13 Camelopardalis''', is a star system located approximately 424 light-years away from the Sun in the constellation of Camelopardalis notable for its dynamically packed system of planets.

Azure Eye is a single star system surrounding an A4V main sequence star, officially named '''Azure Eye'''. The star lies on the Delta Scuti instability strip, causing it to change brightness by 0.04 magnitudes due to helium opacity oscillation with a period of approximately two hours and thirty minutes. It also exhibits Alpha2 Canum Venaticorum variable behaviour, rotating on its axis every twelve hours and thirty minutes - thus, due to slight inhomogeneities in its visible surface, Azure Eye's brightness is also modulated at this period by an amount equal to 0.01 magnitude. This short rotation also causes the star's equator to bulge; its equator is measured at 12.6% wider than its poles. Azure Eye is enriched in the elements silicon, chromium, copper and europium, classifying it as a chemically peculiar Ap star; its planets are observed to exhibit similar abundance patterns.

Azure Eye's planetary system is divided into "circles", analogous to Sol's inner and outer planets. From inward to outward, they are:

*the Inner Circle, comprising of the system's "hot saturn" and several resonant planets orbiting outward from it; inclined to the mean system plane by 8 degrees
*the Carbon Circle, comprising a small ice giant, two mid-size gas giants and several large bodies trapped in resonance with the outer
*the Green Circle, occupying several liquid-specific habitable zones; centered on the water habitable zone but extends inward somewhat
*the Resonant Circle, four large gas giants in a 1:2:4:8 orbital resonance chain
*the Outer Circle, defined as the Kuiper-like debris disk maintained by Victoria and beyond

Azure Eye is also home to several spacefaring civilizations currently united under a single supranational organization known as the Azure Eye Confederacy.
==Composition==
Azure Eye is by far the dominant body in the 13 Cam system, making up 98.85% of all mass in its system. In some aspects, it is comparable to the Solar System - it has several rocky inner planets close to or just inside the habitable zone, a warm debris belt, four large gas giants and a cold debris disk. However, Azure Eye also possesses a system of close-in, resonant planets not unlike many star systems discovered in the early 21st century by the Kepler space telescope, maintained by two nearby warm gas giants. In addition, a large "puffy planet" orbits Azure Eye closely with a period of 8.051 days. A Saturn-sized gas giant also bookends the system in an extremely wide orbit with a semimajor axis of 284.43 ± 0.51 AU.
==Orbits==
All planets in the system orbit Azure Eye on nearly circular orbits, with the exception of EMONGA-2060-BLG-L1714, which is believed to have been captured in the star's birth cluster due to its extremely eccentric and distant orbit along with slightly different isotopic ratios. These orbits, with the exception of the Inner Circle, are all aligned to a common plane, due to the planets having formed out of a circumstellar disk in this plane.

The Inner Circle's orbits are slanted on approximately an 8-degree angle to the system's ecliptic (arbitrarily defined as Ydel's orbital plane). The cause is likely attributable to Uncia, which is by a significant margin the largest planet in this region possessing this tilt; further supporting this is the simultaneous precession of the orbits all 5 of the Inner Circle's planets at a rate similar to that calculated for Uncia in isolation.

guess what? wip

=== Tigris ===
Tigris is Azure Eye's first planet, and is a rare ultra-hot jupiter. It has a mass 220% that of Jupiter, and a radius 146% that of Jupiter.

The planet's tortured atmosphere receives some ten thousand times as much sunlight as Earth, and is dominated by turbulent, planet-sized cyclones filled with mists of refractory minerals which are created near the substellar point, migrate westward around the planet via the mid-latitudes and return to be recycled. Young cyclones are bright red from rubinic cirrus clouds pumped upwards by convection, while older ones appear dark orange or brown due to tausonite (SrTiO3) dredged up from the lower atmosphere.

=== Uncia ===
'''Uncia''' is Azure Eye's second planet, with a mass approximately two thirds that of Jupiter. However, its radius is increased to greater than Jupiter's by extreme irradiation from its host star. It orbits extremely close to its star, completing one orbit in just under ten days.

The planet's proximity to its star results in extreme weather patterns, dominated by a pair of vortices somewhat east of the substellar point that dominate the planet's disk. Much of the planet is covered in clouds of forsterite (Mg2SiO4), save for these vortices, which are clear down to the deep TiVO haze layer, giving them a deep blue colour from Rayleigh scattering.

Uncia's exosphere is not gravitationally bound; it is losing an estimated 100,000 tons of hydrogen and helium per second, creating a large, diffuse gas tail extending approximately 40,000,000 kilometers in its wake.

Despite its proximity to Azure Eye, the planet nonetheless maintains one stable major moon similar to Io, dubbed Snep after a colloquial nickname for the snow leopard. Also like Io, Snep boosts Uncia's magnetosphere significantly, permitting the formation of a plasma torus which can be detected when Uncia transits Azure Eye.

=== Ailurus ===
'''Ailurus''' is a large, iron-rich "super-earth", with a radius of 1.64 earth radii and a mass of 5.45 earth masses. It has an atmosphere with a datum pressure approximately 116 times the pressure of Earth's surface, composed primarily of supercritical carbon dioxide, nitrogen and sulfur dioxide. A tidally locked planet, Ailurus' near side always faces its host star, driving it to stupendous temperatures of nearly 2,000 K. This heat is enough to melt Ailurus' crust, creating a lava ocean on its near side. The edges of this lava ocean host exotic, mineral-based life, and the planet's terminator is dominated by silicon-based organisms believed to have been seeded from Momonga.

Ailurus has four moons: three are small asteroids; the fourth is approximately 44% the diameter of Earth's moon. Ailurus also possesses a hydrogen-rich exosphere produced by the continuing decomposition of water in its atmosphere. Minerals occasionally precipitate out on the planet's night side, acting as the planet's primary economic source of hydrogen due to their water content.

=== Momonga ===
Momonga is a rocky terrestrial planet of approximately 1.15 earth masses. It has a thick atmosphere which exerts a pressure on the planet's surface equal to about 29 bar. Its atmosphere primarily consists of carbon dioxide and nitrogen, with smaller amounts of sulfur dioxide, acetylene, hydrogen sulfide, ethane and argon along with traces of other hydrocarbons. This reducing atmosphere allows the growth of exotic life. Momonga's near side is, like Ailurus, heated to extreme temperatures by its star, reaching 1,400 K at its substellar point. However, since there is less incoming stellar flux, Momonga has a smaller lava sea; a larger area is thus freed for land life and lakes of molten alkali salts. The planet's atmosphere is yellowish by scattered light and bluish by transmitted light, owing to sodium vapour in its atmosphere. Also generated by atmospheric sodium are the Momongan Crowns, which are energetic aurorae which are bright enough to illuminate portions of the planet's night side.

Momonga has three small moons locked in a Laplace resonance, with diameters of 164, 115 and 244 km, respectively.

=== Quokka ===
Quokka is a small, roughly Mars-sized terrestrial planet with only a thin atmosphere of relatively heavy gases. Due to this lack of a substantial atmosphere, its surface is pitted with tens of thousands of impact craters. Tidally locked, Quokka's substellar point reaches 600 degrees Celsius; it glows a faint red when shadowed. The heat causes the rock in this area to soften, flowing at approximately a centimeter per year and erasing craters. Nonetheless, relief in this area persists for unknown reasons, possibly due to blocks of lower-density, stiffer rock rising through solid-state convection. Surprisingly, life - believed to have been transported from Momonga via panspermia - ekes out a tenacious existence on Quokka's surface, forming mats of microbial life on the surface.

=== Mijumaru ===
Mijumaru is a sub-earth with a mass approximately 0.7 times that of Earth. It has an extremely thick atmosphere with a surface pressure of over 300 bar at datum, composed mainly of carbon dioxide and water vapour. Both are potent greenhouse gases; nearly all incoming radiation is trapped and forced back onto the surface. At over 1,500 degrees, the heat here makes Mijumaru the second-hottest planet of the system and causes its surface to break down entirely into a slurry of metal-rich magma with bergs of periclase. The planet is still actively losing water via photodissociation and may end up similar to Venus if it cools down enough.

=== Nergal ===
Nergal is a gas giant with a mass of about 83 times that of Earth. From space, it is a dull magenta color from a combination of Rayleigh scattering, absorption from methane and a deep layer of sulfide clouds.

Nergal only has sixteen moons despite its large mass. This is believed to be because of Laz, its fourth moon which orbits on an inclined, retrograde orbit. It is believed to have been captured, which would have led to a collisional cascade between Nergal's original set of inner moons which later re-accreted to form today's satellite system and Nergal's rings. In contrast, Nergal (number) is a solid body in a wide, inclined orbit, which may have been perturbed by Laz until it arrived in its current orbit due to stellar tides. Two additional minor moons orbit on wide orbits suggesting they were captured. Nergal is also notable for the presence of a large quasi-satellite about the size of Ceres.

==== Laz ====
Laz is by far Nergal's largest moon, at nearly a quarter Earth's mass and two thirds its radius. It is primarily composed of silicates, with an above-average-size iron core. Laz is an uncommon example of an Io-like volcanic world with an active biosphere, utilizing elemental sulfur as a liquid medium and dimethyl sulfone as an energy source, constructed from methane and sulfur dioxide in its atmosphere. Producers on Laz range in colour from light blue to indigo, utilizing the thiozonide anion, to best reflect the large amount of incoming ultraviolet light while taking advantage of the abundant energy, though some primitive plants are light red. Laz's atmosphere is violet due to disulfur gas in its upper stratosphere.

A tidally locked planet, Ailurus' near side always faces its host star, driving it to stupendous temperatures of nearly 2,000 K. This heat is enough to melt Ailurus' crust, creating a lava ocean on its near side.

Minerals occasionally precipitate out on the planet's night side, acting as the planet's primary economic source of hydrogen due to their water content.

=== Momonga ===
Momonga is a rocky terrestrial planet of approximately 0.6 earth masses. It has a relatively thick atmosphere which exerts a pressure on the planet's surface equal to about 4.2 bar. Its atmosphere primarily consists of carbon dioxide and nitrogen, with smaller amounts of sulfur dioxide, acetylene, hydrogen sulfide, ethane and argon. This reducing atmosphere allows the growth of exotic life. Momonga's near side is, like Ailurus, heated to extreme temperatures by its star, reaching 1,800 K at its substellar point. However, since there is less incoming stellar flux, Momonga has a smaller lava sea; a larger area is thus freed for land life and lakes of molten sodium chloride. The planet's atmosphere is yellowish by scattered light and bluish by transmitted light, owing to sodium vapour in its atmosphere. Also generated by atmospheric sodium are the Momongan Crowns, extremely efficient aurorae which are bright enough to illuminate portions of the planet's night side.

Momonga has three small moons locked in a Laplace resonance, with diameters of 164, 115 and 244 km, respectively.

=== Quokka ===
Quokka is a small, roughly Mars-sized terrestrial planet with only a thin atmosphere of relatively heavy gases. Due to this lack of a substantial atmosphere, its surface is pitted with tens of thousands of impact craters. Tidally locked, Quokka's substellar point reaches 900 degrees Celsius; it glows a visible red when shadowed.

Surprisingly, life - believed to have been transported from Momonga via panspermia - ekes out a tenacious existence on Quokka's surface, forming mats of microbial life on the surface.

=== Mijumaru ===
Mijumaru is a sub-earth with a mass approximately 0.4 times that of Earth. It has an extremely thick atmosphere with a surface pressure of over 300 bar at datum, composed mainly of carbon dioxide and water vapour. Both are potent greenhouse gases; nearly all incoming radiation is trapped and forced back onto the surface. At over 1,500 degrees, the heat here makes Mijumaru the hottest planet of the system and causes its surface to break down entirely into a slurry of metal-rich magma with bergs of periclase. The planet is still actively losing water via photodissociation and may end up similar to Venus if it cools down enough.

=== Esmanthea ===
Esmanthea is an ice giant about 12.8 times Earth's mass. No compounds are suitable to form large-scale clouds in the conditions of its atmosphere, though zinc sulfide can condense into wispy, cirrus-like clouds. Copper impurities cause these clouds to phosphoresce as they enter the planet's dark side, producing a green glow where winds carry it furthest, along with a cyan glow where electrical activity in Esmanthea's atmosphere is strongest.

Esmanthea is believed to have undergone a major collision early in its history. Gravitic measurements indicate two large concentrations of mass just above its outer core, analogous to Earth's large low shear-velocity provinces. In addition, the presence of an oversized moon and particles co-rotating with the planet's magnetosphere indicate that a major accretion disk existed around Esmanthea relatively recently. Esmanthea's atmosphere, furthermore, appears to have anomalously large concentrations of sulfides and little-to-no chlorides, which could be explained by upwelling of siderophilic material shortly after the impact along with outgassing of chlorides due to the high temperatures released.

=== Innana ===
Innana is a gas giant 151 times more massive than Earth, or about 47.5% the mass of Jupiter. Its atmosphere, like most gas giants, is dominated by hydrogen and helium, with traces of other gases. Innana, receiving about eighteen times Earth's insolation, is too hot for water clouds. Its upper atmosphere absorbs most light incident on the planet, leaving a relatively cool region around the 5-10 bar level where sulfuric acid can condense.

Innana is the first planet to possess a notable ring system; rings around planets closer to the star suffer from excessive atmospheric drag and Poynting-Robertson forces that disrupt them on astrophysically short timescales. In terms of architecture, Innana's satellite system is similar to Saturn's, with a large number of small-to-medium inner dwarf moons and a handful of small major moons. Notably, one of its moons has a ring of dust along with two narrow rings of boulders.

=== Nergal ===
Nergal is a gas giant with a mass of about 49.6 times that of Earth. From space, it is a dull reddish-brown color from large amounts of tholins in its atmosphere formed by the powerful ultraviolet radiation from its star and carbon-rich atmosphere. Like Innana, it possesses a prominent ring system.

Nergal only has five moons. This is believed to be because of Laz, its fourth moon which orbits on an inclined, retrograde orbit. It is believed to have been captured, which would have led to a collisional cascade between Nergal's original set of inner moons which re-accreted into its three current inner moons. In contrast, Nergal V is a solid body in a wide, inclined orbit, which may have been perturbed by Laz until it arrived in its current orbit due to stellar tides.

=== Achziv ===
Achziv (occasionally Achsiv, Akziv, Axiv, or Arxiv) is a carbon- and iron-rich planet roughly 3.1 times more massive than Earth, named after the micronation of Akhzivland. It has two major moons and a prominent, optically-thick and reflective ring system made of hydrated minerals like talc. This ring system intermittently shades the surface and atmocean, creating strong monsoonal weather patterns across the planet. On discovery, the disproportionate amount of light reflected by Achziv's rings caused scientists to believe it was a "mini-neptune" with poor prospects for life. However, solar- and jovian-lens gravitational telescope arrays were able to resolve the ring system from the planet, confirming its terrestrial nature.

Achziv's innermost moon, Achziv I, is roughly the size of Europa or slightly larger. Similar to Io, its surface is covered in sulfur, which occasionally melts in the daytime heat and reddens. Unusually for a moon so close to a terrestrial planet, it is not tidally locked, instead falling into a 3:2 spin-orbit resonance like Mercury due to its orbit's modest eccentricity of 0.060 ± 0.023. This eccentricity is maintained by perturbations from Achziv's larger and outermost moon, Achziv II, which orbits in a 5:1 mean-motion resonance with the inner. Achziv II is a geologically inactive body similar to the Moon, albeit roughly twice as massive. It also possesses a roughly Deimos-sized submoon and a tenuous xenon exosphere with a pressure of 3.83 ± 0.06 nbar. It is believed that both moons were formed from a major collision involving proto-Achziv and a water-rich body from the outer system, giving Achziv and its moons' orbits a tilt of approximately 18 degrees to the local ecliptic.

Achziv's surface can be divided into a mildly acidic ocean composed predominantly of water and carbon dioxide, overlaid by a layer of supercritical nitrogen and methane with dissolved CO2 and water vapor; critical opalescence at the ceiling of this layer creates a "fog" at ~1.6 km altitude that hides the ocean and lowland regions from above. Above this, the atmosphere transitions into a purely gaseous state. Higher in the atmosphere, clouds of water and even tholins can form.

Azure Eye system

2024-07-12T21:26:40Z

Sogga:

{{Under Construction}}The '''Azure Eye system,''' also known by the anthropic exonym '''13 Camelopardalis''', is a star system located approximately 424 light-years away from the Sun in the constellation of Camelopardalis notable for its dynamically packed system of planets.

Azure Eye is a single star system surrounding an A4V main sequence star, officially named '''Azure Eye'''. The star lies on the Delta Scuti instability strip, causing it to change brightness by 0.04 magnitudes due to helium opacity oscillation with a period of approximately two hours and thirty minutes. It also exhibits Alpha2 Canum Venaticorum variable behaviour, rotating on its axis every twelve hours and thirty minutes - thus, due to slight inhomogeneities in its visible surface, Azure Eye's brightness is also modulated at this period by an amount equal to 0.01 magnitude. This short rotation also causes the star's equator to bulge; its equator is measured at 12.6% wider than its poles. Azure Eye is enriched in the elements silicon, chromium, copper and europium, classifying it as a chemically peculiar Ap star; its planets are observed to exhibit similar abundance patterns.

Azure Eye's planetary system is divided into "circles", analogous to Sol's inner and outer planets. From inward to outward, they are:

*the Inner Circle, comprising of the system's "hot saturn" and several resonant planets orbiting outward from it; inclined to the mean system plane by 8 degrees
*the Carbon Circle, comprising a small ice giant, two mid-size gas giants and several large bodies trapped in resonance with the outer
*the Green Circle, occupying several liquid-specific habitable zones; centered on the water habitable zone but extends inward somewhat
*the Resonant Circle, four large gas giants in a 1:2:4:8 orbital resonance chain
*the Outer Circle, defined as the Kuiper-like debris disk maintained by Victoria and beyond

Azure Eye is also home to several spacefaring civilizations currently united under a single supranational organization known as the Azure Eye Confederacy.
==Composition==
Azure Eye is by far the dominant body in the 13 Cam system, making up 98.85% of all mass in its system. In some aspects, it is comparable to the Solar System - it has several rocky inner planets close to or just inside the habitable zone, a warm debris belt, four large gas giants and a cold debris disk. However, Azure Eye also possesses a system of close-in, resonant planets not unlike many star systems discovered in the early 21st century by the Kepler space telescope, maintained by two nearby warm gas giants. In addition, a large "puffy planet" orbits Azure Eye closely with a period of 8.051 days. A Saturn-sized gas giant also bookends the system in an extremely wide orbit with a semimajor axis of 284.43 ± 0.51 AU.
==Orbits==
All planets in the system orbit Azure Eye on nearly circular orbits, with the exception of EMONGA-2060-BLG-L1714, which is believed to have been captured in the star's birth cluster due to its extremely eccentric and distant orbit along with slightly different isotopic ratios. These orbits, with the exception of the Inner Circle, are all aligned to a common plane, due to the planets having formed out of a circumstellar disk in this plane.

The Inner Circle's orbits are slanted on approximately an 8-degree angle to the system's ecliptic (arbitrarily defined as Ydel's orbital plane). The cause is likely attributable to Uncia, which is by a significant margin the largest planet in this region possessing this tilt; further supporting this is the simultaneous precession of the orbits all 5 of the Inner Circle's planets at a rate similar to that calculated for Uncia in isolation.

==Major Bodies==
guess what? wip

=== Uncia ===
'''Uncia''' is Azure Eye's first planet, with a mass similar to that of Saturn. However, its radius is increased to greater than Jupiter's by extreme irradiation from its host star. It orbits extremely close to its star, completing one orbit every 8.05138386 days.

The planet's proximity to its star results in extreme weather patterns, dominated by a pair of planetary-scale vortices somewhat east of the substellar point. Much of the planet is covered in clouds of forsterite (Mg2SiO4), save for these vortices, which are clear down to the deep TiVO haze layer, giving them a deep blue colour from Rayleigh scattering.

Uncia's exosphere is not gravitationally bound; it is losing an estimated 100,000 tons of hydrogen and helium per second, creating a large, diffuse gas tail extending approximately 40,000,000 kilometers in its wake.

Despite its proximity to Azure Eye, the planet nonetheless maintains one stable major moon similar to Io, dubbed Snep after a colloquial nickname for the snow leopard. Also like Io, Snep boosts Uncia's magnetosphere significantly, permitting the formation of a plasma torus which can be detected when Uncia transits Azure Eye.

=== Ailurus ===
'''Ailurus''' is a large, iron-rich "super-earth". It has an atmosphere with a datum pressure approximately 16 times the pressure of Earth's surface, composed primarily of water vapour, carbon dioxide, nitrogen and sulfur dioxide. A tidally locked planet, Ailurus' near side always faces its host star, driving it to stupendous temperatures of nearly 2,000 K. This heat is enough to melt Ailurus' crust, creating a lava ocean on its near side. The edges of this lava ocean host exotic, mineral-based life, and the planet's terminator is dominated by silicon-based organisms believed to have been seeded from Momonga.

Ailurus has four moons: three are small asteroids; the fourth is approximately 44% the diameter of Earth's moon. Ailurus also possesses a hydrogen-rich exosphere produced by the continuing decomposition of water in its atmosphere. Minerals occasionally precipitate out on the planet's night side, acting as the planet's primary economic source of hydrogen due to their water content.

=== Momonga ===
Momonga is a rocky terrestrial planet of approximately 0.6 earth masses. It has a relatively thick atmosphere which exerts a pressure on the planet's surface equal to about 4.2 bar. Its atmosphere primarily consists of carbon dioxide and nitrogen, with smaller amounts of sulfur dioxide, acetylene, hydrogen sulfide, ethane and argon. This reducing atmosphere allows the growth of exotic life. Momonga's near side is, like Ailurus, heated to extreme temperatures by its star, reaching 1,800 K at its substellar point. However, since there is less incoming stellar flux, Momonga has a smaller lava sea; a larger area is thus freed for land life and lakes of molten sodium chloride. The planet's atmosphere is yellowish by scattered light and bluish by transmitted light, owing to sodium vapour in its atmosphere. Also generated by atmospheric sodium are the Momongan Crowns, extremely efficient aurorae which are bright enough to illuminate portions of the planet's night side.

Momonga has three small moons locked in a Laplace resonance, with diameters of 164, 115 and 244 km, respectively.

=== Quokka ===
Quokka is a small, roughly Mars-sized terrestrial planet with only a thin atmosphere of relatively heavy gases. Due to this lack of a substantial atmosphere, its surface is pitted with tens of thousands of impact craters. Tidally locked, Quokka's substellar point reaches 900 degrees Celsius; it glows a visible red when shadowed. The heat causes the rock in this area to soften, flowing at approximately a centimeter per year and erasing craters. Nonetheless, relief in this area persists for unknown reasons, possibly due to blocks of lower-density, stiffer rock rising through solid-state convection. Surprisingly, life - believed to have been transported from Momonga via panspermia - ekes out a tenacious existence on Quokka's surface, forming mats of microbial life on the surface.

=== Mijumaru ===
Mijumaru is a sub-earth with a mass approximately 0.4 times that of Earth. It has an extremely thick atmosphere with a surface pressure of over 300 bar at datum, composed mainly of carbon dioxide and water vapour. Both are potent greenhouse gases; nearly all incoming radiation is trapped and forced back onto the surface. At over 1,500 degrees, the heat here makes Mijumaru the hottest planet of the system and causes its surface to break down entirely into a slurry of metal-rich magma with bergs of periclase. The planet is still actively losing water via photodissociation and may end up similar to Venus if it cools down enough.

=== Esmanthea ===
Esmanthea is an ice giant about 12.8 times Earth's mass. No compounds are suitable to form large-scale clouds in the conditions of its atmosphere, though zinc sulfide can condense into wispy, cirrus-like clouds. Copper impurities cause these clouds to phosphoresce as they enter the planet's dark side, producing a green glow where winds carry it furthest, along with a cyan glow where electrical activity in Esmanthea's atmosphere is strongest.

Esmanthea is believed to have undergone a major collision early in its history. Gravitic measurements indicate two large concentrations of mass just above its outer core, analogous to Earth's large low shear-velocity provinces. In addition, the presence of an oversized moon and particles co-rotating with the planet's magnetosphere indicate that a major accretion disk existed around Esmanthea relatively recently. Esmanthea's atmosphere, furthermore, appears to have anomalously large concentrations of sulfides and little-to-no chlorides, which could be explained by upwelling of siderophilic material shortly after the impact along with outgassing of chlorides due to the high temperatures released.

=== Innana ===
Innana is a gas giant 151 times more massive than Earth, or about 47.5% the mass of Jupiter. Its atmosphere, like most gas giants, is dominated by hydrogen and helium, with traces of other gases. Innana, receiving about eighteen times Earth's insolation, is too hot for water clouds. Its upper atmosphere absorbs most light incident on the planet, leaving a relatively cool region around the 5-10 bar level where sulfuric acid can condense.

Innana is the first planet to possess a notable ring system; rings around planets closer to the star suffer from excessive atmospheric drag and Poynting-Robertson forces that disrupt them on astrophysically short timescales. In terms of architecture, Innana's satellite system is similar to Saturn's, with a large number of small-to-medium inner dwarf moons and a handful of small major moons. Notably, one of its moons has a ring of dust along with two narrow rings of boulders.

=== Nergal ===
Nergal is a gas giant with a mass of about 49.6 times that of Earth. From space, it is a dull reddish-brown color from large amounts of tholins in its atmosphere formed by the powerful ultraviolet radiation from its star and carbon-rich atmosphere. Like Innana, it possesses a prominent ring system.

Nergal only has five moons. This is believed to be because of Laz, its fourth moon which orbits on an inclined, retrograde orbit. It is believed to have been captured, which would have led to a collisional cascade between Nergal's original set of inner moons which re-accreted into its three current inner moons. In contrast, Nergal V is a solid body in a wide, inclined orbit, which may have been perturbed by Laz until it arrived in its current orbit due to stellar tides.

=== Achziv ===
Achziv (occasionally Achsiv, Akziv, Axiv, or Arxiv) is a carbon- and iron-rich planet roughly 3.1 times more massive than Earth, named after the micronation of Akhzivland. It has two major moons and a prominent, optically-thick and reflective ring system made of hydrated minerals like talc. This ring system intermittently shades the surface and atmocean, creating strong monsoonal weather patterns across the planet. On discovery, the disproportionate amount of light reflected by Achziv's rings caused scientists to believe it was a "mini-neptune" with poor prospects for life. However, solar- and jovian-lens gravitational telescope arrays were able to resolve the ring system from the planet, confirming its terrestrial nature.

Achziv's innermost moon, Achziv I, is roughly the size of Europa or slightly larger. Similar to Io, its surface is covered in sulfur, which occasionally melts in the daytime heat and reddens. Unusually for a moon so close to a terrestrial planet, it is not tidally locked, instead falling into a 3:2 spin-orbit resonance like Mercury due to its orbit's modest eccentricity of 0.060 ± 0.023. This eccentricity is maintained by perturbations from Achziv's larger and outermost moon, Achziv II, which orbits in a 5:1 mean-motion resonance with the inner. Achziv II is a geologically inactive body similar to the Moon, albeit roughly twice as massive. It also possesses a roughly Deimos-sized submoon and a tenuous xenon exosphere with a pressure of 3.83 ± 0.06 nbar. It is believed that both moons were formed from a major collision involving proto-Achziv and a water-rich body from the outer system, giving Achziv and its moons' orbits a tilt of approximately 18 degrees to the local ecliptic.

Uncia's exosphere is not gravitationally bound; it is losing an estimated 100,000 tons of hydrogen and helium per second, creating a large, diffuse gas tail extending approximately 40,000,000 kilometers in its wake.

Despite its proximity to Azure Eye, the planet nonetheless maintains one stable major moon similar to Io, dubbed Snep after a colloquial nickname for the snow leopard. Also like Io, Snep boosts Uncia's magnetosphere significantly, permitting the formation of a plasma torus which can be detected when Uncia transits Azure Eye.

=== Ailurus ===
'''Ailurus''' is a large, iron-rich "super-earth". It has an atmosphere with a datum pressure approximately 16 times the pressure of Earth's surface, composed primarily of water vapour, carbon dioxide, nitrogen and sulfur dioxide. A tidally locked planet, Ailurus' near side always faces its host star, driving it to stupendous temperatures of nearly 2,000 K. This heat is enough to melt Ailurus' crust, creating a lava ocean on its near side. The edges of this lava ocean host exotic, mineral-based life, and the planet's terminator is dominated by silicon-based organisms believed to have been seeded from Momonga.

Ailurus has four moons: three are small asteroids; the fourth is approximately 44% the diameter of Earth's moon. Ailurus also possesses a hydrogen-rich exosphere produced by the continuing decomposition of water in its atmosphere. Minerals occasionally precipitate out on the planet's night side, acting as the planet's primary economic source of hydrogen due to their water content.

=== Momonga ===
Momonga is a rocky terrestrial planet of approximately 0.6 earth masses. It has a relatively thick atmosphere which exerts a pressure on the planet's surface equal to about 4.2 bar. Its atmosphere primarily consists of carbon dioxide and nitrogen, with smaller amounts of sulfur dioxide, acetylene, hydrogen sulfide, ethane and argon. This reducing atmosphere allows the growth of exotic life. Momonga's near side is, like Ailurus, heated to extreme temperatures by its star, reaching 1,800 K at its substellar point. However, since there is less incoming stellar flux, Momonga has a smaller lava sea; a larger area is thus freed for land life and lakes of molten sodium chloride. The planet's atmosphere is yellowish by scattered light and bluish by transmitted light, owing to sodium vapour in its atmosphere. Also generated by atmospheric sodium are the Momongan Crowns, extremely efficient aurorae which are bright enough to illuminate portions of the planet's night side.

Momonga has three small moons locked in a Laplace resonance, with diameters of 164, 115 and 244 km, respectively.

=== Quokka ===
Quokka is a small, roughly Mars-sized terrestrial planet with only a thin atmosphere of relatively heavy gases. Due to this lack of a substantial atmosphere, its surface is pitted with tens of thousands of impact craters. Tidally locked, Quokka's substellar point reaches 900 degrees Celsius; it glows a visible red when shadowed. The heat causes the rock in this area to soften, flowing at approximately a centimeter per year and erasing craters. Nonetheless, relief in this area persists for unknown reasons, possibly due to blocks of lower-density, stiffer rock rising through solid-state convection. Surprisingly, life - believed to have been transported from Momonga via panspermia - ekes out a tenacious existence on Quokka's surface, forming mats of microbial life on the surface.

=== Mijumaru ===
Mijumaru is a sub-earth with a mass approximately 0.4 times that of Earth. It has an extremely thick atmosphere with a surface pressure of over 300 bar at datum, composed mainly of carbon dioxide and water vapour. Both are potent greenhouse gases; nearly all incoming radiation is trapped and forced back onto the surface. At over 1,500 degrees, the heat here makes Mijumaru the hottest planet of the system and causes its surface to break down entirely into a slurry of metal-rich magma with bergs of periclase. The planet is still actively losing water via photodissociation and may end up similar to Venus if it cools down enough.

=== Esmanthea ===
Esmanthea is an ice giant about 12.8 times Earth's mass. No compounds are suitable to form large-scale clouds in the conditions of its atmosphere, though zinc sulfide can condense into wispy, cirrus-like clouds. Copper impurities cause these clouds to phosphoresce as they enter the planet's dark side, producing a green glow where winds carry it furthest, along with a cyan glow where electrical activity in Esmanthea's atmosphere is strongest.

Esmanthea is believed to have undergone a major collision early in its history. Gravitic measurements indicate two large concentrations of mass just above its outer core, analogous to Earth's large low shear-velocity provinces. In addition, the presence of an oversized moon and particles co-rotating with the planet's magnetosphere indicate that a major accretion disk existed around Esmanthea relatively recently. Esmanthea's atmosphere, furthermore, appears to have anomalously large concentrations of sulfides and little-to-no chlorides, which could be explained by upwelling of siderophilic material shortly after the impact along with outgassing of chlorides due to the high temperatures released.

The '''Azure Eye system,''' also known by the anthropic exonym '''13 Camelopardalis''', is a star system located approximately 424 light-years away from the Sun in the constellation of Camelopardalis notable for its dynamically packed system of planets.

Azure Eye is a single star system surrounding an A4V main sequence star, officially named '''Azure Eye'''. The star lies on the Delta Scuti instability strip, causing it to change brightness by 0.04 magnitudes due to helium opacity oscillation with a period of approximately two hours and thirty minutes. It also exhibits Alpha2 Canum Venaticorum variable behaviour, rotating on its axis every twelve hours and thirty minutes - thus, due to slight inhomogeneities in its visible surface, Azure Eye's brightness is also modulated at this period by an amount equal to 0.01 magnitude. Azure Eye is enriched in the elements silicon, chromium, and europium, classifying it as a chemically peculiar Ap star; its planets are observed to exhibit similar abundance patterns.

Azure Eye's planetary system is divided into "circles", analogous to Sol's inner and outer planets. From inward to outward, they are:

*the Inner Circle, comprising of the system's "hot saturn" and several resonant planets orbiting outward from it; inclined to the mean system plane by 8 degrees
*the Carbon Circle, comprising a small ice giant, two mid-size gas giants and several large bodies trapped in resonance with the outer
*the Green Circle, occupying several liquid-specific habitable zones; centered on the water habitable zone but extends inward somewhat
*the Resonant Circle, four large gas giants in a 1:2:4:8 orbital resonance chain
*the Outer Circle, defined as the Kuiper-like debris disk maintained by Victoria and beyond

Azure Eye is also home to several spacefaring civilizations currently united under a single supranational organization known as the Azure Eye Confederacy.
