Metis. Jupiter Moons. Metis is the innermost known satellite of Jupiter. It was named after a Titaness who was a consort of Zeus (Jupiter). Metis and Adrastea lie within Jupiter's main ring and may be the source of material for the ring. Very little is known about Metis.
This Galileo image is the the first image of the small moon that shows its irregular shape. Metis orbits Jupiter in the zone between the planet's ring and the larger Galilean satellites. The longest dimension of Metis is approximately 60 kilometers (37 miles) across.
