Discovery of Thelxinoe

9 February 2003

Thelxinoe is a tiny irregular moon of Jupiter, only about two kilometres across, discovered in February 2003 by a team led by Scott Sheppard at the University of Hawaii in a survey of the outer region of Jupiter's system. It moves on a distant, inclined orbit in the retrograde direction, opposite to Jupiter's rotation, and belongs to the Ananke group, a family of moons that are thought to be fragments of a single captured body. It was known by a provisional designation until it was given its present name in 2005. The name is taken from Greek mythology, where Thelxinoe is one of the Muses in an early tradition. Like the other small outer moons it is known only from telescope observations.
