Discovery of Fenrir

13 December 2004

Fenrir is a tiny irregular moon of Saturn, only a few kilometers across, found in images from December 2004 by astronomers led by Scott Sheppard. It orbits at a great distance from the planet, in the opposite direction to Saturn's rotation, which is typical of moons captured after the planet formed, and is part of the Norse group. It is named after Fenrir, the monstrous wolf of Norse mythology, a son of the god Loki who is fated to kill Odin at Ragnarök. It is one of the smaller known moons of Saturn.
