Discovery Despina was discovered in July 1989 by the Voyager 2 science team. Overview Despina is a tiny moon located within Neptune's faint ring system. The irregularly-shaped moon orbits Neptune every eight hours, circling in the same direction as Neptune's own rotation. Despina remains close to Neptune's equatorial plane.
