One of a quartet* of small moons, with Leda, Elara and
Himalia, that orbit Jupiter
far beyond the four large Galilean Moons. Like the other moons in this group,
Lysithea's orbit carries it around Jupiter at a distance of
more than 100,000 kilometres. With a diameter of just 36 kilometres, Lysithea is by far the
smallest of its particular group of satellites - Himalia, by comparison, has a
diameter of 186 kilometres.
* The Himalia group might possibly be a quintet rather than a quartet, as the small moon Dia also possibly belongs within this group.
