'Elara' (, Attic Greek Ελάρα) is a prograde irregular satellite of Jupiter. It was discovered by Charles Dillon Perrine at Lick Observatory in 1905 and is named after the mother by Zeus of the giant Tityus.^[4]
Elara did not receive its present name until 1975; before then, it was simply known as 'Jupiter VII'. It was sometimes called "Hera"^[5] between 1955 and 1975.
Elara belongs to the Himalia group, five moons orbiting between 11 and 13 Gm from Jupiter at an inclination of about 27.5°. Its orbital elements are as of January 2000. They are continuously changing due to Solar and planetary perturbations.
