The Moon of Uranus
Features of Oberon
The most notable features of Oberon are its craters. These craters are more numerous and much larger than those on Ariel and Titania. Some of these craters exhibit bright rays of ejecta material similar to those on Jupiter's moon, Callisto. Several images of Oberon show a lone mountain peak rising 4 miles above the surface. In the southern hemisphere, large faults can be seen crossing the surface. This may be evidence of some type of geologic activity early in the moon's history. Oberon has no detectable atmosphere and no magnetic field.
