Lysithea /laɪˈsɪθiə/ is a prograde irregular satellite of Jupiter. It was discovered by Seth Barnes Nicholson in 1938 at Mount Wilson Observatory[1] and is named after the mythological Lysithea, daughter of Oceanus and one of Zeus' lovers.[10]
Lysithea did not receive its present name until 1975; before then, it was simply known as Jupiter X. It was sometimes called "Demeter"[11] from 1955 to 1975.
It belongs to the Himalia group, moons orbiting between 11 and 13 Gm from Jupiter at an inclination of about 28.3°.[12] Its orbital elements are as of January 2000. They are continuously changing due to solar and planetary perturbations. It is gray[failed verification] in color (B−V=0.72, V−R=0.36, V−I=0.74) and intermediate between C-type and P-type asteroids.[13][6]
