Psamathe (moon)

Psamathe is one of the numerous natural satellites of the planet Neptune. It was discovered in 1989 by a team of astronomers using data from the Voyager 2 spacecraft during its flyby of Neptune. Psamathe is classified as a irregular moon, which means it has an orbit that is more distant and eccentric compared to regular moons. It is also one of the outermost known moons of Neptune.
