Known Space -- Sol -- Jupiter -- | Adrastea |
Adrastea is the second of Jupiter's satellites. It is one of the smallest moons in the solar system. Metis and Adrastea orbit inside the synchronous orbit radius and inside the Roche limit. They are small enough to avoid tidal disruption but their orbits will eventually decay.
