The fourth moon of Neptune in order from
the planet. Galatea was discovered by the Voyager Imaging Team in July 1989.
It is named after one of the Nereids of Greek legend and is also known as
Neptune VI. Like the five other inner moons discovered during the 1989 flyby
of Voyager 2, Galatea is among the darkest objects in the solar system.
