This picture is part of NASA's Voyager 2 imaging sequence of Ariel, a moon of Uranus taken on January 24, 1986. The complexity of Ariel's surface indicates that a variety of geologic processes have occurred.
Distinct bright patches are visible on Ariel, the brightest of Uranus' five largest satellites. NASA's Voyager 2 obtained this image Jan. 22, 1986, from a distance of 2.52 million kilometers (1.56 million miles).
On Jan. 24, 1986, NASA's Voyager 2 obtained this color picture of the Uranian moon, Ariel. Most of the visible surface consists of relatively intensely cratered terrain transected by fault scarps and fault-bounded valleys (graben).
