120347 Salacia is a large planetoid in the Kuiper belt. It was discovered on September 22, 2004 by Henry G. Roe, Michael E. Brown and Kristina M. Barkume at the Palomar Observatory. It is probably a dwarf planet. Salacia's diameter is estimated to be 850 kilometres (530 mi) due to a low albedo. It has been observed 100 times, with precovery images back to 1982. Salacia orbits the Sun at an average distance slightly greater than that of Pluto.
(120347) 2004 SB60 was assigned the name Salacia /sæˈleɪʃə/ on 18 February 2011. Salacia is the goddess of salt water and the wife of Neptune.
Salacia has one natural satellite, Actaea, that orbits its primary every 5.494 days. The moon's name, Actaea, was assigned on the same date. Actaea is a nereid or sea nymph.
