Minmus is a small moon of Kerbin. From the surface of Kerbin or Mun, it is a purple speck which appears to slightly oscillate vertically. This is a result of viewing its rotation from afar. Up close, it is mint green in appearance with what seem to be icy buttes, large hills, and frozen lakes. The highest areas are over 5.7 km in altitude. It is more difficult to reach Minmus orbit than Mun orbit, but easier to land.
- Synodic Period from Kerbin's Surface: 14 days, 3 hours, 1 second (1220401 seconds)
Synchronous orbit around Minmus is possible at an altitude of 0.00 m.
Minmus has a much rougher surface than Kerbin or Mun, with substantial areas over 6 km high. The vast majority of the surface is rolling hills, with lakes (of frozen methane?) concentrated near the equator. The lakes are almost perfectly flat and mostly at datum altitude (0 m).
Rotational/Inertial transition: 100,000 m
- Minmus is no longer tidally locked to Kerbin.
- Minmus' mass reduced. 
- Synchronous orbit is now possible. Previously, it would have required an altitude of 0.00 m, outside Minmus' sphere of influence.
