S/2003 J 16 is a natural satellite of Jupiter. It was discovered by a team of astronomers led by Brett J. Gladman in 2003.
S/2003 J 16 is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 0.137 AU (20.5 Gm) in 600 days, at an inclination of 151° to the ecliptic (149° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.333. It belongs to the Ananke group of retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 million km, at inclinations of roughly 150°.
