Discovery of Carme

30 July 1938

Carme is an irregular outer moon of Jupiter, discovered in July 1938 by Seth Nicholson at the Mount Wilson Observatory in California. It orbits far from the planet on a tilted path in the retrograde direction, and it is the largest member and namesake of the Carme group, whose members share similar orbits and are thought to be fragments of a single captured body. Carme is about 46 kilometres across and has a reddish colour. It was known as Jupiter XI until 1975, when it was named after a figure of Greek mythology who was loved by Zeus and was the mother of Britomartis.
