ⓘ Lysithea (moon)

Lysithea is a prograde non-spherical moon of Jupiter. It was found by Seth Barnes Nicholson in 1938 at Mount Wilson Observatory and is named after the mythological Lysithea, daughter of Oceanus and one of Zeus lovers.

Lysithea did not get its present name until 1975; before then, it was simply known as Jupiter X. It was sometimes called "Demeter" from 1955 to 1975.

It belongs to the Himalia group, five moons orbiting between 11.000.000 and 13.000.000 km from Jupiter at an inclination of about 28.3°. Its orbital elements are as of January 2000. They are changing a lot due to Solar and planetary perturbations.
