Adrastea Adrastea, the distributor of rewards and punishments, was the daughter of Jupiter and Ananke. Discovered by graduate student David Jewitt (working under Danielson) in 1979 (Voyager 1). Metis and Adrastea orbit inside the synchronous orbit radius and inside the Roche limit. They may be small enough to avoid tidal disruption but their orbits will eventually decay. Adrastea is one of the smallest moons in the solar system.
