Oberon In Color
This image of Oberon shows several large impact craters towards the
center of the picture. Many of the crater floors are covered by an
unknown dark material. On the bottom-left limb,
a high mountain rises 6 kilometers (4 miles) above its surroundings.
Bright rays similar to those seen on Jupiter's
moon Callisto, can be found on Oberon's surface.
