Short Description Puck is an inner moon of Uranus. It was discovered in December 1985 by the Voyager 2 spacecraft. The name Puck follows the convention of naming Uranus's moons after characters from Shakespeare. The orbit of Puck lies between the rings of Uranus and the first of Uranus's large moons, Miranda. Puck is approximately spherical in shape and has diameter of about 162 km. It has a dark, heavily cratered surface, which shows spectral signs of water ice. Puck is the largest small inner moon of Uranus, which orbits inside the orbit of Miranda. Puck (moon) - Wikipedia, the free encyclopedia Discovered by Stephen P.
