S/2003 J 9 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 many of Jupiter's recently found moons, it is probably an irregular satellite, a small and distant body on a tilted, elongated orbit that was probably captured long ago. Such moons are generally thought to be fragments of larger bodies broken up by collisions. It is known only from telescope measurements of its motion, so little else can be stated with confidence about its size or origin.
