Elara is a prograde irregular satellite of Jupiter. It was discovered by Charles Dillon Perrine at Lick Observatory, in 1905. It is the eighth largest moon of Jupiter. The moon is named after Elara, one of Zeus's lovers and the mother of the giant Tityos.
Elara did not actually receive it's name until 1975. Before that, it was known simply as Jupiter VII.
