Laomedeia, also known as Neptune XII and previously as S/2002 N 3, is an irregular moon of Neptune. It was discovered on 13 August 2002 by Matthew Holman, JJ Kavelaars, Tommy Grav, Wesley Fraser, and Dan Milisavljevic at Cerro Tololo Inter-American Observatory in Chile. Named after one of the Nereids from Greek mythology, Laomedeia follows a distant, highly eccentric, and highly inclined orbit around Neptune with an average orbital period of about 8.7 Earth years. Its orbit is prograde, meaning it revolves around Neptune in the same direction as the planet's orbit around the Sun.
