Eeloo is a Dwarf Planet that was released in version 0.18.2 as a Christmas gift to the KSP community. It is the seventh planet from Kerbol, though it occasionally intersects Jool's orbit, passing in front of it. It is also locked in a 3:2 resonance with Jool. It is most likely an analogue of the ice moon Europa, or the dwarf planet Pluto.
The surface of Eeloo is relatively smooth and covered in ice, with deep canyons exposing the surface below.
