Earth is the third planet from the Sun and is the only body known to have life. It is one of the four 'rocky' planets, the others are Mercury, Venus, and Mars. The Moon is the only natural satellite orbiting the earth.

The Earth is close to an oblate spheroid, but, in Orbiter it's modeled as a sphere, its mean diameter is 6371.01 km, but gravitational calculations include the J coefficients given in the table to the right. The sidereal day is 86164.092 seconds, the obliquity is 23.439291°.

Spaceports

The stock Orbiter includes 35 bases, some of which include details such as runways, landing pads, buildings, etc, some only include a marker to depict its location.
