Jupiter's Moon Adrastea -- Adrastea [a-DRAS-tee-uh] is the second innermost known satellite of Jupiter.

Adrastea was the daughter of Jupiter and Ananke and the distributor of rewards and punishments. Adrastea and Metis lie within Jupiter's main ring and may be the source of material for the ring. Very little is known about Adrastea.
