Object guide
Oberon is a heavily cratered outer moon of Uranus with a mixed surface of old terrains and fracture systems. Oberon is approximately 1,522.8 km across.
How to observe Oberon
Oberon is resolved as a separate world mainly through imaging or spacecraft data; visually, its relationship to uranus is the key observing context.
