| − | '''Mun''', also known as '''the Mun''' and sometimes written as '''Mün''', is a relatively large [[:Category:Moons|moon]] orbiting [[Kerbin]]. It can be thought of as an analogue to Earth's own moon, which frequently is simply called “[[w:Moon|the Moon]]” (Latin: ''Luna'').
| |
| − | | |
| − | It is gray in appearance with [[w:Impact crater|craters]] of various sizes and [[w:Mountain|mountains]] exceeding 5029 m in height. The gravitational pull on the surface is 1.63 m/s², approximately 5/6 and 8.18 m/s² lower than that of Kerbin and about the surface gravity of Earth's Moon (1.624 m/s²). It is possible to [[Tutorial:Mun Landing|land on the Mun]] or use it for [[Tutorial: Gravity Assist|gravity assist]]s (gravitational slingshots) to outer bodies such as [[Minmus]] or into [[Kerbol]] orbit, though such maneuvers do not save very much fuel and are more imprecise. It is, however, useful for plane changes with proper timing.
| |
| − | | |
| − | New players should note that Mun (like the majority of celestial bodies in the game) has no [[atmosphere]]. That means [[parachute]]s do not work when descending to the surface.
| |
| − | | |
| − | There are [[KerbNet#Anomaly Detection|anomalous]] geological formations that can be found on the surface of the Mun.
| |
| − | | |
| − | Synchronous orbit around the Mun is not possible, since it would have to occur at an altitude of {{OrbitAltitude | period=138984.376574476 | mass=9.76002360215472e20 | radius=200000 |factor=k}}, beyond the Mun's sphere of influence. However, putting your spacecraft just outside Mun's SOI and having the same semi-major axis would make it appear stationary. A normal 25 km orbit can be achieved using around 800 m/s delta V. With the 600 m/s provided by a jetpack Kerbals can fly to very low orbit if they use a very efficient ascent profile. This excludes flying over high obstacles early in the flight. A semi-synchronous orbit with half the rotation period of the Mun is possible at approximately 1797.41 kilometers.

| − | |The Mun, is a large satellite orbiting Kerbin. It is mostly gray in appearance, with craters of various sizes dotting its otherwise smooth surface.<br />

| |
| − | [[File:Mun heights.svg|thumb|left|The minimum height for the different inclinations]]
| |
| − | The Mun's terrain is rough, grey, and scarred by craters. Its low-lying areas tend to be darker in colour. The Mun also features canyons which can be hundreds of meters deep and a few kilometers long.
| |
| − | | |
| − | The Mun's highest points reach a maximum altitude of more than 7061 m near the south pole at 152.33° W and 82.52° S. This altitude permits 10× [[Time warp|warp]], allowing crashes with terrain while being in a seemingly stable orbit. Its lowest point, below -247 m, is on the northern hemisphere south-west of the large northern crater at 76.63° W and 35.32° N.
| |
| − | | |
| − | When terrain scatter is activated in the graphics settings, the Mun has rocks scattered on its surface. Like all terrain scatters, these rocks are strictly cosmetic and do not collide with ships or Kerbals.
| |
| − | | |
| − | The Mun is peppered with procedural impact craters making Mun landing more difficult. Previously the lowest point with an altitude of 0 m was on the east side of a large crater, at 35.42° E, 8.27° N.
| |
| − | | |
| − | The Hell Kraken has been encountered on the Mun, with objects being thrown out of Kerbin's sphere of influence upon reloading the craft.
| |
| − | | |
| − | The Mun also has several hidden surprises for explorers to find:

| − | |content=
| |
| − | * There are three large stone arches. Due to their size they can be spotted easily from a low (<10 km) orbit near the equator.
| |
| − | * There is a memorial honouring Neil Armstrong, the first man on the moon. It can be found inside one of the largest craters, near the south wall. It is at nearly the same coordinates where Apollo 11 first landed on the moon. It appears as a tiny white dot from low orbit.
| |
| − | * There are three monoliths ("Munoliths"). These are very hard to find because of their small size. One is partially underground, one is on top of a steep hill and is at the bottom of a deep, steep-sided valley.

| |
| − | [[File:MunBiomeMap.png|left|thumb|The biomes on Mun]]
| |
| − | The Mun has, with a total of 17, the most biomes of any celestial body. Each major crater is a distinct biome, which gives them somewhat official names; however, like all biome names, they are fairly generic. The Midlands and Highlands biomes each have a biome applied to any of the nameless large craters within them. The polar regions also have three different biomes. There are seven distinct craters and two basins.{{clear|left}}

| − | == Observation from Kerbin ==
| |
| − | | |
| − | The Mun's orbit keeps it directly above Kerbin's equator. Because the Mun is tidally locked to Kerbin with a perfectly circular, non-inclined orbit, exactly 50% of the Mun's surface (excluding areas on the edge obscured by the Mun's mountains) is ever visible from Kerbin.
| |
| − | | |
| − | Due to the Mun's non-inclined orbit, [[eclipse]]s occur every time the Mun goes between the Sun and Kerbin. Due to graphic engine limitations, these solar eclipses currently do not make the sky black, or darken the land. However, [[solar panel]]s will become blocked by the Mun in an eclipse and become useless for a short period of time.
| |
| − | | |
| − | A full Kerbolar eclipse can be observed while landed at KSC starting about Year 1, Day 351, 5h:40m, and ending (being partial again) somewhere around Year 1, Day 352, 0h:22m. Not sure of other occurences or locations, but this one at KSC is confirmed (unless game times and positions of bodies varies between players). A Kerbolar eclipse happens every synodic orbital period, or about 6 days 3 hours, somewhere on Kerbin's equator.
| |
| − | | |
| − | Although the game graphics depict Mun as totally covering the solar disk during an eclipse, based on the given diameters of Sun and Mun and their distances from Kerbin, Sun has a larger apparent size. For observers on and near Kerbin, solar eclipses would be annular.
| |
| − | | |
| − | == Observation of Kerbin ==
| |
| − | | |
| − | Because Mun is tidally locked to Kerbin, Kerbin is only visible from 50% of the Mun's surface, and Kerbin never sets or rises as seen from the Mun. The Mun longitude for which Kerbin remains directly above in the sky (at the [[w:Zenith|zenith]]) is about 47 degrees east. The Mun's equator is coplanar with Kerbin's, so any location on the Mun's equator that faces Kerbin will also face Kerbin's equator. Kerbin is not tidally locked to the Mun, so any point on the Mun where Kerbin is not obscured by the Mun's landscape will be able to observe every point on Kerbin as Kerbin rotates. Kerbin's [[w:Synodic period|synodic rotational period]] with the Mun is 25617.909 seconds, or 1.18323 Kerbin solar days.
| |
| − | | |
| − | == Science ==
| |
| − | | |
| − | Although the [[science]]-multipliers of Mun's surface and orbit are quite low compared to that of other planets and moons, Mun is comparably easy to reach and has a very large number of biomes which all yield different science results. This makes it - together with [[Minmus]] - the main source of science points during the midgame.

| − | == Trivia ==
| |
| − | [[File:StartGameMenu.0.21.1.png|thumb|''Mün or Bust'' in the game menu]]
| |
| − | * After its implementation, many fans began calling the body '''Mün''', pronounced the same as "moon", believing the original spelling to be a mistake. However, several of the game's developers have been heard referring to it as '''Mun''', pronounced "muhn". In the "Surface of the Mün" title screen, a crashed lander resembling a [[Kerbal X]] has the words "Mün or Bust" scrawled on the side. Both spellings are generally accepted, however the spelling in-game is '''The Mun''', despite the fact that planets can have non-english letters in them.
| |
| − | * Mun was Kerbin's, and indeed the game's, very first moon.
| |
| − | * Mun's orbit is perfectly circular and has zero orbital inclination. Such an orbit in reality would be very unlikely since this would require precise positioning of any dust/bodies that created it during the planetary system's formation, as well as the absence of a central star or other planets.
| |
| − | ** This was likely done to make it easier to reach for new players.
| |
| − | ** This also makes it an excellent guideline to use for placing satellites into exact inclinations around Kerbin. By setting Mun as target, the relative inclination described by the maneuver tool also represents the inclination of the satellite's orbit to Kerbin
| |
| − | * Prior to {{version|0.14.2}}, the tallest points on the munar surface were no higher than roughly 600m.
| |
| − | * Before introduction of procedural terrain the Mun's highest point was within 45° latitude of the equator, had an altitude of 2967 m and was located at 129.64° W, 0.97° N, on the north side of a canyon which was on the east edge of a large crater.
| |
| − | * Prior to {{version|0.14.3}} a KSC could be found on the Mun.
| |
| − | * The Mun is considerably larger than 1/10 the size of the real world Moon.
| |
| − | * The Mun is one of the few bodies in the solar system that is almost completely manually colored (i.e., it uses a color map). Most other planets and moons are colored procedurally or with a lot of procedural colors doing the work. The only procedural colors on the Mun are associated with the procedural craters and a basic noise. The other planets which are manually colored are Tylo (Aside from a tenuous coat of height color map) and Jool (As a gas giant, it must be manually colored)
| |
| − | * Before 0.90 the Mun was one of the few bodies with multiple [[biomes]].
