Leda

Leda, in astronomy, one of the 39 known moons, or natural satellites, of Jupiter.

Leda, in Greek mythology, daughter of Thestios, king of Aetolia, and wife of Tyndareus, king of Sparta. According to most legends, she was seduced by Zeus, who visited her in the form of a swan. She bore two eggs; from one issued Castor and Pollux, from the other Helen (and, in some myths, Clytemnestra). Castor and Clytemnestra, however, are usually said to be the offspring of Tyndareus.

In Greek legend, the daughter of King Thestius of Aetolia and wife of King Tyndareus of Lacedaemon. Visited by Zeus in the form of a swan, she conceived Helen of Troy. Zeus was also sometimes said to be the father of her son Pollux, while Leda's own husband, Tyndareus, was held to be the father of his twin, Castor (see Dioscuri). Tyndareus was also the father of Leda's daughter Clytemnestra, who married Agamemnon.
