Himalia, or Jupiter VI, is the largest irregular satellite of Jupiter, with a diameter of at least 140 km (90 mi). It is the fifth largest Jovian satellite, after the four Galilean moons. It was discovered by Charles Dillon Perrine at the Lick Observatory on 3 December 1904. Himalia is named after the nymph Himalia, who bore three sons of Zeus (the Greek equivalent of Jupiter).
