S/2011 J 2 was discovered in 2011 by Scott S. Sheppard with digital images obtained with the Magellan-Baade 6.5 meter telescope at Las Campanas Observatory


S/2011 J 2 was found at magnitude 23.5 (more than 6 million times fainter than the naked eye can see) on images taken on Sept. 27, 2011. Little is known about this new moon of Jupiter besides its approximate orbit, which is backwards compared to the direction of Jupiter's rotation.

How S/2011 J2 Got its Name

S/2011 J2 was so designated because it is a satellite (S) that was discovered in 2011, and was the second satellite of Jupiter (J) to be found that year.
