Eeloo is a dwarf planet that was originally released in version 0.18.2 of KSP1 as a Christmas gift to the KSP community. It is the seventh and farthest planet from Kerbol most of the time, though its orbit intersects Jool's, passing in front of it for a minority of its revolution period. The two planets are locked in a 3:2 resonance, which, coupled with their different inclinations, ensures they cannot collide.

Eeloo has just 3.5% more gravity than the Mun and is very similar in size. Like the Mun, it has no atmosphere. The physical characteristics of Eeloo are most likely an analog of the ice moon Europa, and its orbit is similar to that of Pluto, though both bodies are known to have a tenuous atmosphere.

Eeloo's relatively large distance from Kerbol reduces solar power to approximately 4% at Eeloo periapsis and 1.4% at Eeloo apoapsis of the values seen at Kerbin. Bringing additional panels, or an alternate power source (e.g.: RTGs) is recommended.

In KSP 2, Eeloo has an axial tilt of approximately 33°, meaning that at certain times of its year, the poles will never see sunlight.

In-game Descriptions

KSP 1:

“

There’s been a considerable amount of controversy around the status of Eeloo as being a proper planet or a just “lump of ice going around the Sun”. The debate is still ongoing, since most academic summits held to address the issue have devolved into, on good days, petty name calling, and on worse ones, all-out brawls.

— Kerbal Astronomical Society

”

KSP 2:

“

Eeloo is Kerbol's most distant orbiting body. This dwarf planet seems to enjoy its lonely, highly eccentric orbit, though it does dip into Jool's for brief visits. Missions here are costly, given Eeloo's orbit, low gravity, lack of atmosphere, and spotty solar power potential. Even so, the difficult trip is worth it to see the frozen cliffs up close!

”

Topography

The surface of Eeloo is relatively smooth and covered in gray-white ice, with deep canyons exposing the brownish rock below. A few craters are visible, but not nearly as one might expect for a body without an atmosphere. Its highest points are near the equator and are almost 3.9 km high, while the lower areas can go lower than sea level.

Eeloo's surface lacks ground scatter, suggesting the ice on the surface is subject to erosion of some sort.

It originally had an atmosphere, but it has been removed because the renderer for it doesn't work on bodies smaller than about Duna's size.^[1]

In KSP2, the "cracks" on Eeloo's surface are deep canyons.

Biomes

Eeloo has a total of 11 biomes.

Orbits

Eeloo's distant, eccentric, and inclined orbit, in addition to its low gravity, make encounters challenging. Its distance from Kerbin also tends to make missions very lengthy.

A synchronous orbit around Eeloo is possible, at an altitude of ~683.9 km.

Eeloo's eccentric orbit means that at specific points, it is incredibly close to Jool and in fact that for brief periods, is closer to the Sun than Jool. This means that the effect of Jool's gravitational assists in an Eeloo mission can, with the right timing, drastically reduce the time spent on the mission. However, the rarity of this event means that a landed Eeloo craft will have to wait many years to reverse this action precisely and make it back to Kerbin.

Easter egg

Spoiler: Easter egg about the atmosphere

Like its real-life analog Pluto, Eeloo is mentioned in the following Gravity Scan to have a thin atmosphere. Eeloo's atmosphere is not actually present in the game, serving only as worldbuilding.

 {  
   EelooSrfLanded = There appears to be a teneous atmospheric coating around the planet. But it is too thin to affect any spacecraft landing here.

Trivia

In KSP1, there were once plans for Eeloo to become the moon of a second gas planet and have an active surface, with cryovolcanic phenomena.^[1]^[2] It is unknown what Eeloo's parent planet was intended to look like, but according to former developer NovaSilisko Eeloo was to be the innermost moon of three other major moons.^[2]

In Gigastructural Engineering (GE) -- a mod for the strategy game Stellaris -- the Kerbol System can be configured in the settings menu to generate at the start of the game. In GE's rendition of the Kerbol System, Eeloo is a deactivated Attack Moon.
