Ariel is named after a sky spirit in Shakespeare's The Tempest. The moon is relatively free of large impact craters and has a complex surface consisting of cratered terrain, smooth plains, and rugged terrain cross-cut by scarps, ridges, and interconnected canyons, some of which are hundreds of miles long and more than seven miles deep. There is also evidence of volcanism, tectonics, and cryolava flows.
Ariel is the fourth largest of the 27 known moons of Uranus and much of the detailed knowledge of Ariel derives from a single flyby of Uranus by Voyager II which photographed about a third of the moon's surface.
