Discovery of Larissa

24 May 1981

Larissa is a moon of Neptune, first seen on 24 May 1981 by a team of astronomers led by Harold Reitsema during a stellar occultation, when a star briefly dimmed as the object passed in front of it. The observation suggested the presence of a body near Neptune, but it was not confirmed as a moon until the Voyager 2 spacecraft flew past the planet in 1989 and took images of it. Larissa is an irregular, potato-shaped object and one of Neptune's inner moons, orbiting close to the planet. It is named after a nymph of Greek mythology who was a lover of the sea god Poseidon, the counterpart of the Roman Neptune.
