History of Earth
Formation
Some 4.5 billion years ago materials in the inner solar system are pulled by gravity create the earth.
Shortly after Earth's formation a mars sized planet 10% the Earth's mass called Theia collided sending thousands of debris flying off into space, this debris will later form rings and then our moon. However the way Theia hit earth was different this time witch caused to spinning in a retrograde rotation.

Geophysical characteristics
Size and Shape
The shape of Earth is a near perfect spherical ball, with an average diameter of 12,742 kilometers (7,918 mi), making it the fifth largest of the Solar System's planetary sized objects and largest among its terrestrial ones. Due to Earth's rotation its shape is bulged around the Equator and slightly flattened at the poles, resulting in a 43 kilometers (27 mi) larger diameter at the equator than at the poles.
