Isonoe is a small irregular moon of Jupiter, only about four kilometres across, and a member of the Carme group of retrograde moons. They orbit Jupiter far out, in the opposite direction to the planet's rotation, and are believed to be fragments of a larger captured body. Isonoe was discovered in a survey of the outer moons by astronomers at the University of Hawaii, in a batch of new moons announced in 2000. Its name comes from Greek mythology, and it ends in e, as the naming convention requires for retrograde moons.
