Dres is the fifth planet in the Kerbol star system. It is located between Duna and Jool in a somewhat eccentric and inclined orbit. It is considered to be the Ceres analog for the game. It is similar to Moho and Eeloo in that it has no atmosphere and no natural satellites (aside from a ring system). Dres has the least gravity of any planet in the Kerbol system. Dres is considered a dwarf planet by the game because it has not "cleared its neighborhood", due to the presence of "Dres-teroids" nearby. However, the "Dres-troids" are actually in orbit around Dres, by definition, making them part of a ring system. Therefore, Dres may also be considered a planet.

In-game Description

Dres is a very small planet. It was the first planet considered to be a dwarf. Its orbit is highly irregular and, together with its size, it took a long time to discover since half the time it was not where scientists expected to find a planet.

Due to its nature of frequenting the bad parts of space, this dwarf planet was officially labeled as Not to be trusted by the scientific community.

Kerbal Astronomical Society


The surface of Dres appears light grey and is rocky and uneven, similar to that of Mün, with a surface covered in regolith rubble. Unlike Mün, Dres has large patches of what appears to be ice. The highest points are just under 5.7 km in altitude. One notable geographic feature is a canyon just south of the equator, which is several kilometers deep.


The surface of Dres has several craters. However, unlike other planetary bodies, none are very prominent, the largest being slightly under 13 km in diameter.

In total, 42 craters have been positively identified. Another 5 are still waiting for confirmation. The spreading of the craters is biased to the western, particularly the northwestern, hemisphere of Dres.

Quadrant No. of craters (%) No. of Craters
North-East 19.0% 8
South-East 7.5% 4
North-West 42.9% 18
South-West 28.6% 12
Total 100% 42


Dres has 8 biomes.
