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°.

Earth is one of the twelve original bodies in Orbiter since the earliest known version. Its orbit was defined in the Earth.cfg file in Orbiter 2001 and Orbiter 2002, but was later defined in the Vsop87.dll file beginning with Orbiter 2002-P1.

Orbital characteristics

Earth is the third planet from the Sun, after Mercury and Venus, with a semimajor axis in Orbiter of about 1.49598×1011 km, and an orbital eccentricity of about 0.0167, and an inclination of 0.00005° (0.00000087 radian).

Physical characteristics

The Earth is modeled in Orbiter as a sphere 6371.01 km in radius with a mass of about 5.974×1024 kg. The Sidereal rotation period is just under 24 hours. At the surface the acceleration due to gravity is 9.78 m/s2</sup, and the Escape velocity|escape velocity]] is 11.186 km/s.

Geological features

In Orbiter 2016, Earth is modeled as a sphere with elevations approximating the elevations on the real Earth, including sea level. Included in the stock version are files for Antartic Stations, Cities, Impact Features Islands, Mountains and volcanos, Tracking Stations, and some miscellaneous features. Files are located in your Orbiter\Config\Earth\Marker directory.

Natural satellites

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.
