Thalassa

Thalassa, also known as Neptune IV, is a natural satellite of the outer planet, Neptune. Thalassa was discovered in September 1989 by the Voyager Imagery Team.

Surface FeaturesEdit

The surface of Thalassa is unknown, because we haven't been close enough to the Neptunian moon to accurately see all of its features.
