How Jupiter LI Got its Name
This moon is still awaiting an official name. Since its discovery is now confirmed, it is temporarily being called Jupiter LI, which means it is the 51st confirmed moon discovered at Jupiter. It was originally called S/2010 J1 was so designated because it is a satellite (S) that was discovered in 2010, and was the 1st satellite of Jupiter (J) to be found that year.
