Lysithea (lye-sith'-ee-ə or lə-sith'-ee-ə, IPA: [laɪˈsɪθiə, lɨˈsɪθiə]; Greek Λυσιθέα) 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.[3] Seth Barnes Nicholson (November 12, 1891 – July 2, 1963) was an American astronomer. ...
