'''Dres''' is the fifth celestial body in the [[Kerbol]] star system, and is the first dwarf planet. It is located between [[Duna]] and [[Jool]] in a somewhat eccentric and inclined orbit. It is considered to be the [[w:Ceres|Ceres]] analog for the game. It is similar to [[Moho]] and [[Eeloo]] in that it has no [[atmosphere]] and no natural satellites.  Dres has the least gravity of any planet in the Kerbol system.  Dres is a dwarf planet because it has not "cleared its neighborhood", due to the presence of "Dres-teroids" nearby.

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 [[w:Regolith|regolith]] rubble. Unlike the Mun, Dres has large patches of what appears to be ice. The highest points are just under 5.7&nbsp;km in altitude.

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

“ 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

 ”


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.

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 N/A 42


Biomes

Interplanetary travel

From a 12 km Dres escape trajectory, the requirements for attaining an intercept trajectory of other celestials are:

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.

  • 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."
