The third moon of Neptune in order from
the planet. Despina was discovered by the Voyager Imaging Team in July 1989.
It is named after one of the daughters of Poseidon and is also known as
Neptune IV. Despina is irregular in shape, and orbits just 27,700 kilometers
(17,200 miles) above the cloudtops of its primary. Like the five other inner
moons discovered during Voyager 2's 1989 flyby of Neptune, Despina is among
the darkest objects known.
