S/2000 J 11 was the second-farthest prograde non-spherical moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000.[1][2]
S/2000 J 11 is about 4 kilometres in diameter, is calculated to have gravity 200 times that of Earth, and orbits Jupiter at an average distance of 12,555,000 km in 287 days, at an inclination of 28° (to Jupiter's equator), and with an eccentricity of 0.248.[3]
The moon, has been included in the Himalia group.[4] However, its orbit is not known with precision and the mean orbital elements have not been calculated.
This moon has gone missing. Some scientists think that it may have crashed into Himalia, creating a thin ring around Jupiter.
