Discovery of Bestla

13 December 2004

Bestla is a small irregular moon of Saturn, only about seven kilometres across, which moves on a distant, tilted and elongated orbit in the direction opposite to the planet's rotation. It was discovered in images taken in December 2004 by a team led by Scott Sheppard with telescopes on Mauna Kea in Hawaii, and the find was announced in 2005. Bestla belongs to the Norse group of Saturn's moons, which astronomers believe are fragments of a larger body captured by the planet long ago. It is named after a giantess in Norse mythology who was the mother of the god Odin and of his brothers Vili and Ve.
