Despina or Neptune V is the third closest moon to Neptune. It is named after Despina, a nymph who was a daughter of Poseidon. 

Despina was found in late July 1989 from the images taken by the Voyager 2 probe. It was given the designation S/1989 N 3.

Despina is not a sphere and shows no sign of any geological changes.
