Moho is the innermost planet of the Kerbol star system and the Mercury analogue for Kerbal Space Program. It lacks an atmosphere and natural satellites.
Moho's inclined and eccentric orbit, lack of atmosphere, (for aerobraking) or moons (for gravity assists) make encountering the planet a very difficult endeavor.

In-game Description
| “ | Moho figures in Kerbal mythology as a fiery place with oceans of flowing lava. In reality, however, it's much less interesting. Scientists speculate about possible ways to make it awesome like in the stories. Some of those ideas have led to new breakthroughs in aerospace technology. |

Naming
Moho gets its name from the Mohorovičić discontinuity; the boundary between the Earth's crust and mantle.
Topography
Moho's surface ranges from light brown highlands to dark brown basins, possibly the product of volcanism. Its highest point is in its northern hemisphere at an altitude of 6817 m. Moho's heavy cratering suggests erosion. Tidal friction with Kerbol most likely causes airless Moho's erosion by inducing volcanic periods that fill craters.
Moho has a very deep well at its geographic north pole, called the Mohole by fans in reference to Project Mohole, and the Northern Sinkhole by scientific instruments. Despite, according to the Map View, the apparent existence of another hole at the geographic south pole, one does not exist. The Mohole is about 4.6 kilometers deep.[1] The hole is a glitch in the procedural generation of terrain; many other bodies with land at the north pole have similar bugs.[2]
The Mohole can destroy craft and Kerbals that fall into it.
Biomes
Moho has 12 biomes. It is one of two bodies (the other being Ike) that have their own North and South Pole biome.

Orbital Statistics
Mohosynchronous and semi-synchronous orbits are impossible — they would require altitudes of 18 182.08 km and 11 361.48 km respectively, both of which are beyond Moho's sphere of influence.

Solar System Counterpart
Moho is the apparent Kerbol System analog of the planet Mercury. Both share a similar cratered landscape, like most bodies with little to no atmosphere. Due to the lack of an atmosphere to retain heat, Moho and Mercury are freezing on the night side and, relative to Earth, extremely hot on the day side. Both planets are the closest to their respective stars and lack natural satellites.
However, Moho has a brown surface, while Mercury has a dark grey surface. In addition, Mercury has a tenuous atmosphere of about 10⁻¹³ kPa while Moho has no atmosphere; although, a pressure of 10⁻¹³ kPa (≃ 10⁻¹⁵ atm) would be rendered "unmeasurable" by the PresMat Barometer and register in KSP as a vacuum.

Changes
- Added biomes
- New, procedurally generated, textures added, with higher detail craters.
- Entirely changed more cratered surface.
- Color changed from red to brown.
- No more superheated atmosphere.
- No longer tidally locked.
- Mass reduced.
- Initial Release
