S/2000 J 11 was[1] an object believed to be the second-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.[2][3]

S/2000 J 11 has not been recovered and is no longer considered a satellite candidate.[1] One theory is that it crashed into Himalia, creating a faint ring around Jupiter.[4]

The satellite was initially included in the Himalia group,[5] but its mean orbital elements were never calculated.

S/2000 J 11 was believed to be about 4 kilometres in diameter, orbiting Jupiter at an average distance of 13 milion km in 287 days, at an inclination of 28° (to Jupiter's equator), and with an eccentricity of 0.248.[6]
