==Fizikalne karakteristike==

Miranda's surface may be mostly water ice, with the low density body being made of [[silicate]] rock and [[methane]]-related [[organic compound]]s. Miranda's surface is criss-crossed by huge canyons up to [[1 E4 m|20 kilometres]] (12 miles) deep, with patchwork regions of broken terrain indicating intense geological activity in the moon's past. Large grooved structures, called [[coronae]], may be the result of upwelling warm ice. It is thought that this activity is powered by [[tidal force]]s from Uranus. Another theory, now considered less likely, suggests that Miranda was at some point struck by a massive object that shattered the moon. Fragments then resettled into different positions forming the current strange pattern.
