On the facade of the Khazneh, between the first two columns (left to right) and the last two columns are two equestrian groups (the Dioscuri—Castor and Pollux, twin sons of Zeus and Leda). According to classical mythology, Leda was one of the women with whom Zeus had an affair.

(Greek mythology) a queen of Sparta who was raped by Zeus who had taken the form of a swan; Helen of Troy was conceived in the rape of Leda

A moon of Jupiter was discovered by Charles T. Kowal at the Mount Palomar Observatory on September 14, 1974. Leda is also designated as "Jupiter XIII". In Greek mythology, Leda was queen of Sparta who was the mother of Castor, Polydeuces, Clytemnestra and Helen of Troy.

Leda is Jupiter's ninth and smallest moon. Leda is 9.9 miles (16 km) in diameter and orbits at an average of 6,900,000 miles (11,094,000 km) from Jupiter. Leda has a mass of 5.68 x 10 15 kg. It orbits Jupiter in 238.72 (Earth) days. Very little is known about Leda. Leda was discovered by Charles Kowal in 1974.

Leda (lee'-dÉ™, ; Greek Λήδα), or Jupiter XIII, is a prograde irregular satellite of Jupiter that was discovered by Charles T. Kowal at the Mount Palomar Observatory on September 14, 1974, right after three nights' worth of photographic plates had been taken (September 11 through 13; Leda appears on all of them). It is named after Leda, the queen of Sparta who was the mother of Castor, Polydeuces, Clytemnestra and Helen of Troy (Zeus, in the form of a swan, was the father).

In Greek mythology, Leda was the daughter of the Aetolian king Thestius, and the wife of Tyndareus, the king of Sparta.
