Introduction
Earth is the third planet from the Sun, orbiting at a mean distance of 150 million kilometers. It is an oblate spheroid, which means that the equatorial diameter of 12,756 km is larger than the polar diameter of 12,714 km. It has a mass of 6 x 1024 kg. The altitude of the surface features range from 11 km below to 9 km above sea level. 70% of its surface is liquid water, which makes it unique in the solar system.
