Dres is the fifth planet in the Kerbol 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

Topography

In KSP, the surface of Dres appears light grey and is rocky and uneven, similar to that of the Mun, with a surface covered in regolith rubble. Unlike the Mun, 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 which is called the "Dres Canyon" just south of the equator, which is several kilometers deep.

Cratering

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.

Biomes

Dres has 8 biomes.

Trivia

• 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."
  • However, it did not stop, and some people say that Dres is not real.
• According to the International Astronomical 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.
  • According to the International Astronomical Union, this technically means that Dres has the most moons in the Kerbol System, as there is not an official definition of what qualifies as a moon.
• In KSP, 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)
• In the KSPedia, there is more info on Dres. "Some astronomers have noticed variations in gravitational measurements around Dres. While only slight, perhaps there is something more to this gray dwarf."
