Neso is a natural satellite of the planet Neptune. It was discovered in 1989 by astronomers at the University of Arizona using images taken by the Voyager 2 spacecraft during its flyby of Neptune. Neso is one of Neptune's outer moons and is notable for its irregular, elongated shape, as well as its relatively large distance from Neptune, which is over 48,000 kilometers (about 30,000 miles).
