Oberon
1,523 kmdiameter
Details
Oberon is the outermost and second-largest of Uranus' major moons. Voyager 2 found an old, heavily cratered surface, dark material on crater floors, and a mountain rising about 6 kilometers above the surrounding terrain.
Voyager 2’s partial view of Oberon showed an old, heavily cratered surface, dark material on several crater floors and a limb feature rising about 6 kilometers above the surrounding terrain. The images show less obvious resurfacing than on Ariel, Titania or Miranda. Interior models permit a remaining ocean layer, but the surface observations do not confirm one.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
