Psamathe is one of the outer moons of Neptune and was discovered in 2003 by a team of astronomers led by Matthew J. Holman. It is named after one of the Nereids, the sea nymphs of Greek mythology who were the daughters of Nereus, the Old Man of the Sea. Psamathe is a small, irregularly shaped moon that measures about 40 kilometers (25 miles) across its longest dimension. It has a highly eccentric orbit, which means it varies greatly in distance from Neptune, ranging from about 46.7 million km (29.1 million miles) to 73.3 million km (45.5 million miles). Its orbital period is about 2,366 Earth days (6.48 years). Little is known about Psamathe's surface, geology, or composition, but it is likely composed of water ice and other light materials, similar to the other outer moons of Neptune. Psamathe's small size and distant orbit make it difficult to study, and it has only been observed a few times by telescopes.
