Corsito (Virgil 1b) is the second moon from Cyrene (Virgil I), Virgil system, located in Vanduul territory. In contrast to its sister moon Jai (Virgil 1a), it has a dark, slightly blue surface and reflects about half as much light. An enormous crater with a large ring of bright carbon dioxide ice on its floor lies in its northern hemisphere, creating a single bright point of light.
