S/2003 J 2 is an unnamed non-spherical moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard and David C. Jewitt and was announced on March 4, 2003 [1][2] As of 2006, it is Jupiter's farthest known moon.
S/2003 J 2 is about two kilometres in diameter, and orbits Jupiter at an average distance of 29,540,000 km in 980 days, at an inclination of 154° to the ecliptic (152° to Jupiter's equator) and with an orbital eccentricity of 0.2255.[3][4][5]
It seems to belong to a group all of its own, with a distant and retrograde orbit.
