Minmus as seen from orbit in version 0.15.2

A full projection map of Minmus as of version 0.15 and above

Minmus is a small moon of Kerbin, and only available in versions 0.15 and higher. 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 5.7km in altitude. It is more difficult to reach Minmus orbit than Mün orbit, but easier to land.

Characteristics

• Equatorial Radius: 60 km

• Mass: 4.234e19 kg

• Density: 46.79 g/cm^3

• Surface Gravity: 0.785 m/s^2 or 0.080 g

• Gravitational parameter: 2.825505 km^3/s^2[[1]]

• Escape velocity from surface: 306.89 m/s

• Rotation Period: ~299.272 hours; Rotation: ~1.203 degrees per hour, or ~0.35 m/s (believed to be tidally locked to Kerbin)

• Axial Tilt/Obliquity: 6° with respect to its orbital plane, 0° with respect to the ecliptic.(?)

• Theoretical Synchronous Orbit altitude: 4303.59 km; Stationary Orbit velocity: 25 m/s

Note, this Stationary orbit cannot actually be achieved, as any satellite or vessel attempting to achieve this orbit will be re-captured by Kerbin.

Orbital Characteristics

• Parent Body: Kerbin

• Semi-Major Axis: 47000 km

• Velocity: 274.1 m/s

• Inclination: 6°

• Longitude of Ascending Node: 78°

• Argument of Periapsis: 0°

• Mean Anomaly at Epoch UT = 0.0: 1.56206968 radians (approx.)

• Orbital Period: 12 days, 11 hours, 16 minutes, 19 seconds (1077379 seconds)

• Sphere of influence: ~ 2,713 km or 45 body radii

Topography

Minmus has a much rougher surface than Kerbin or Mün, with substantial areas over 4 km high. The vast majority of the surface is rolling hills, with lakes of frozen methane concentrated near the equator.[2] The lakes are almost perfectly flat and mostly at datum altitude (0 m).

Reference Frames

Rotational/Inertial transition: 100,000 m
