Sao (moon)
moon of Neptune
Sao is a non-spherical moon of Neptune. It was found by Matthew J. Holman et al. on August 14, 2019.
Sao orbits Neptune at a distance of about 22.4 million km and is about 44 kilometers in diameter (assuming an albedo of 0.04).
Sao has a very inclined and eccentric orbit seen on the diagram in relation to other non-sperical moons of Neptune.
Sao, or Neptune XI, like many of the farther moons of Neptune, is named after one of the Nereids; Sao was associated with sailing and is referred to as "The rescuer" or "Safety". Before the announcement of its name on February 3, 2007 (IAUC 8802), Sao was known provisionally as S/2002 N 2.
