Kerbin is the third planet from Kerbol and one of only two bodies in the Kerbol System known to sustain liquid surface water. Kerbin is orbited by two natural permanent satellites, the Mun and Minmus. It has a circumference of approximately 3,770km. Of the six rocky planets in the system, it is the second largest and second most massive behind Eve. Kerbin is the birthplace and home of Kerbalkind.
