S/2000 J11
These three images show the rediscovery of S/2000 J11 from the Magellan telescope at Las Campanas, Chile. Each image was taken about 30 minutes apart, which allows the Jupiter moon S/2000 J11, marked by a green box, to be seen moving relative to the steady-state of background stars. Jupiter is out of the field-of-view but Jupiter's bright glare can be seen on the left side of the images.

With a prograde orbit and a radius of about 2 km, S/2000 J11 is the smallest member of the Himalia group (made up of Himalia, Leda, Lysithea, and Elara).

S/2000 J11 was discovered in 2000 by S.S. Sheppard, D.C. Jewitt, Y. Fernandez and G. Magnier using the University of Hawaii's 2.2 m (88 inch) telescope atop Mauna Kea. S/2000 J11 was then lost in Jupiter's bright glare for several years. S/2000 J11 was rediscovered in images obtained by the Magellan Telescope in 2010 and 2011.

How S/2000 J11 Got its Name:
S/2000 J11 was so designated because it is a satellite (S) that was discovered in 2000, and was the 11th satellite of Jupiter (J) to be found that year.
