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 of asteroids). 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"; in other terms, it has asteroids in close proximity.

In-game Description

Dres is a very small planet. It was the first planet considered to be a dwarf. It’s orbit is highly irregular and together with it’s 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 Mun, 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.

  • Added "Dres-teroid" belt (will appear randomly after achieving a flyby)
  • Added biomes
  • Initial Release


  • Dres was the subject of a Kerbal meme referring to the status of Dres as an interesting place or a boring place.
    • KSP Youtuber Felsmak created a youtube video about how Dres is boring.
    • Felsmak later made a video about how Dres is a hoax. This was a parody of the Bielefeld Conspiracy, not a serious video.
    • This had led some forumers to start the Dres Appreciation thread, and others to fight back.
    • That led to a flame war which essentially bled into unrelated forum posts.
    • Felsmak closed the thread on his Dres Hoax video, stating that "This Dres meme has gotten kinda spammy now, it seems, and I don't really want to encourage it any further."
  • According to the International Astronautical Union, Dres would be considered a planet as it does not share an orbit with any other objects.
  • The Dres-teroid belt is not an analogue of the asteroid belt, but rather a diffuse ring of debris orbiting Dres. This means that Dres actually has an unknown and variable amount of natural satellites.
    • This technically means that Dres has the most moons in the solar system.
  • Dres, Vall, Eeloo, and Moho are the only bodies in the solar system that are colored completely using a PQSMod_HeightColorMap. (Colors are based purely on the terrain height)
