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 IAUC 8087: Satellites of Jupiter 2003 March 4 (discovery)Sheppard, S. S.; and Jewitt, D.

 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.MPEC 2003-E11: S/2003 J 1, 2003 J 2, 2003 J 3, 2003 J 4, 2003 J 5, 2003 J 6, 2003 J 7 2003 March 4 (discovery and ephemeris)Mean orbital elements from NASA JPL (August 2006)Current (2004 July 14, JD= 2453200.5) orbital elements as reported by IAU-MPC NSES are a= 0.2024818 AU, e=0.1882469 i=153.52114

It seems to belong to a group all of its own, with a distant and retrograde orbit.
