S/2000 J 11 is the outermost prograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000. [ [http://cfa-www.harvard.edu/iauc/07500/07555.html IAUC 7555: "Satellites of Jupiter"] 2001 January 5 (discovery)] [ [http://cfa-www.harvard.edu/mpec/K01/K01A29.html MPEC 2001-A29: "S/2000 J 7, S/2000 J 8, S/2000 J 9, S/2000 J 10, S/2000 J 11"] 2001 January 15 (discovery and ephemeris)]

S/2000 J 11 is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 12.555 Gm (million km) in 287 days, at an inclination of 28° (to Jupiter's equator), and with an eccentricity of 0.248.Sheppard, S.

The satellite, has been initially included in the Himalia group.Sheppard, S. S.; Jewitt, D. C.; [http://www.ifa.hawaii.edu/~jewitt/papers/JSATS/SJ2003.pdf "An abundant population of small irregular satellites around Jupiter"] , Nature, 423 (May 2003), pp. 261-263 ] However, its orbit isn't known with adequate precision and the mean orbital elements haven't been calculated.
