[[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.

[[Earth]] is the planet we live on. It is the third planet from the [[Sun]]. It is the only planet known to have life on it. Lots of scientists think the earth formed around 4.5 billion years ago. It is one of four rocky planets on the inside of the Solar System. The other three are [[Mercury]], [[Venus]] and [[Mars]].

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 the third planet from the [[Sun]], after [[Mercury]] and [[Venus]], with a [[Semi-major axis|semimajor axis]] in [[Orbiter]] of about 1.49598×10<sup>11</sup> km, and an orbital [[Eccentricity|eccentricity]] of about 0.0167, and

== Physical characteristics ==
 
−
The Earth is modeled in Orbiter as a sphere 6371.01 km in radius with a mass of about 5.974×10<sup>24</sup> kg. The Sidereal rotation period is just under 24 hours. At the surface the acceleration due to [[gravity]] is 9.78 m/s<sup>2</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.
