Miranda 

Miranda, a moon of Neptune discovered in 1948 by Gerard Kuiper is one of the most interesting satellites in the solar system. When Voyager 2 flew by Miranda in 1986, it took numerous pictures of the surface and found a vast and diverse array of fractures, faults, grooves and craters which were unlike anything ever seen.

Plate tectonics and internal activity may have caused the large faults seen all around the surface while other troughs and canyons may have been produced by the unusual formation of the moon.

Scientists theorize that Miranda may have shattered as much as five times during the course of its history and reassembled itself into a conglomerate of strange and haphazard geological formations.

Its radius is 235.8 kilometers making it a relatively small sized oon of Neptune. The surface temperature is measured to be -187° C or -335° F with icy material on the crust.
