Oberon (Sol 7e)

Moons

Oberon (Sol 7e) is a moon of Uranus (Sol VII), United Empire of Earth (UEE). Slightly red in color, it likely obtained its hue from the accretion of materials from other parts of the Uranus system. Meteorite impacts have also knocked ice from the surface, leaving dark, non-ice…
