S/2003 J 18 is a provisional designation for a small natural satellite of Jupiter, announced in 2003 after a ground-based survey for faint moons around the planet. Like most of Jupiter's recently found moons, it is probably an irregular satellite: a small, distant body on a tilted, elongated orbit, most likely captured from the wider population of asteroids and comets. Objects of this kind are often fragments of larger bodies broken apart by collisions. Its few known details come from telescope observations of its faint motion, so little else can be stated with confidence.
