Minmus

Minmus/Data

Minmus is the smaller moon of Kerbin. From the surface of Kerbin or Mun, it is a cyan speck one or two pixels wide which appears to slightly oscillate vertically. This is a result of viewing its rotation from afar. Up close, it is off white 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 requires more delta-v to reach Minmus orbit than Mun orbit, however it is easier to land on the surface and return.

Orbital characteristics

The synodic period from Kerbin's surface is 14 days, 3 hours and 1 second (1220401 seconds). A synchronous orbit around Minmus is possible at an altitude of 357.94 km.

It is important to be careful when attempting to return to Kerbin from Minmus, as Minmus' high orbit makes it very easy to escape Kerbin's sphere of influence entirely. However, this means that a base on or in orbit around Minmus would make a convenient refueling station for vessels leaving the Kerbin system.

Topography

Minmus has a very uneven surface, with substantial areas over 5 km high and a maximum terrain elevation of 5725 m. The vast majority of the surface is rolling hills, with lakes of a frozen substance (or salt, as Minmus is too close to the Sun for water ice to form) concentrated near the equator. The addition of science in version 0.22 allows surface samples, and the taking of a surface sample form Minmus says that it is a "crystalline substance, definitely not edible though". Currently there are no separate biomes, but during Kerbalcon 2013 the developers stated that it would have biomes as of 0.23^[outdated].^{[citation needed]}

The lakes are almost perfectly flat and mostly at datum altitude (0 m). Minmus also has some mesas which are so high compared to Minmus' sphere of influence, that they still count as in orbit according to the navigation tools. Unless the player manually switches the navball to Surface mode, this makes landing on these plateaus more challenging, as the direction marker and speed will not automatically correct for the rotation of the surface.

For most landings which are not on a plateau or in a lake, the touchdown altitude are usually between 2000m and 2500m.

Jumping on this moon will make the kerbonaut ascend 10m from the ground.

Trivia

• The name "Minmus" may be derived from the Latin word "minimus", which denotes the smallest member of a group of beings or creatures. Minmus is the smallest member of the Kerbin system.
• It's also possible that Minmus is named after Saturn's moon Mimas.
• Minmus is also the name for the fifth and smallest toe on the foot.
• It is possible to land and takeoff from Minmus with the EVA jetpack at 100% fuel.
• If 2HOT Thermometer is used on surface, it shows a temperature of -0.007, which is just enough for water to freeze.
• If SC-9001 Science Jr. is used near or on Minmus in career mode, it will state that its test samples start to glow due to radiation. This might cause Minmus to have a higher temperature than Mun

Changes

0.17

• Minmus is no longer tidally locked to Kerbin.
• Minmus' mass reduced.
• Synchronous orbit is now possible. Previously, it would have required an altitude of 4 302.99 km, outside Minmus' sphere of influence.
