NotesThe small, dark moon Fenrir is part of a group of some hundred irregular moons orbiting in the outer regions of the Saturn system, known collectively as the Norse group. Like the other members of the group, Fenrir has a retrograde orbit, and thus is likely to be an object captured by Saturn's gravity, rather than having formed within the Saturnian system.
