Kerbin is a planet which is home to the Space Center and the main focus of Kerbal Space Program. It has two moons, named Mun and Minmus. It is the third planet in orbit around the M class star Kerbol. It is the third largest planet after Jool and Eve, and the fourth largest celestial object around Kerbol (the moon Tylo being slightly larger).

Topography
Kerbin has a roughly equal distribution of liquid water and solid land, with polar icecaps and scattered deserts. Between versions 0.7 and 0.14.1 (including the current demo version of 0.13.3), some mountain ranges exceeded 600 m in height. The highest point was at approximately 900 m altitude.[1] In versions 0.14.2 and later, a new terrain engine has resulted in mountains exceeding 3 km high. The tallest mountain at least 3750 m.[2]
Atmosphere
Kerbin has an atmosphere of unknown composition, though because Kerbin has plants and animals, it can be assumed there is O2, N2, and CO2. The atmosphere gets exponentially less dense as altitude increases (5 km scale height), and ends at 69,077.55 meters.[3]

As of 0.15.2, atmospheric temperature varies with altitude in a roughly Earth-like manner.[4]
Natural Satellites
In 0.12+ , Kerbin had a single moon, the Mün. With 0.15, Kerbin has a second satellite, Minmus.
Orbital Statistics
The geosynchronous orbit of Kerbal is at an altitude of 2868.572 km above Kerbal (sea level). The speed of the satellite is 1009.0 m/s and it has an orbital periode resonating with 1 Kerbal day (6 hours or 21600 seconds.) For a semisynchronous orbit of ½ Kerbal day (3 hours or 10800 seconds) an orbit of 1585.063 km above Kerbal is needed with a velocity of 1271.2 m/s
