Laomedeia (/ˌleɪ.oʊmᵻˈdiːə/ LAY-o-mə-DEE-ə or /ˌleɪ.oʊmᵻˈdaɪ.ə/ LAY-o-mə-DY-ə; Greek: Λαομήδεια), also known as Neptune XII, is a prograde irregular satellite of Neptune. It was discovered by Matthew J. Holman, et al. on August 13, 2002.[5] Before the announcement of its name on February 3, 2007 (IAUC 8802), it was known as S/2002 N 3.
It orbits Neptune at a distance of about 23,571,000 km and is about 42 kilometers in diameter (assuming albedo of 0.04).[4] It is named after Laomedeia, one of the 50 Nereids.
