A retrograde outer satellite of Jupiter, mean distance 23 629 000 km; also known as Jupiter VIII. It orbits the planet in 743.6 days at an inclination of 151°.4, and has an orbital eccentricity of 0.41, one of the greatest eccentricities of any Jovian moon. Pasiphae is 60 km in diameter and was discovered in 1908 by the English astronomer Philibert Jacques Melotte (1880–1961). It is the largest of the so-called Pasiphae retrograde irregular group of Jovian moons, the other members of which are Helike, Eurydome, Autonoe, Sponde, Megaclite, Sinope, Hegemone, Aoede, Callirrhoe, Cyllene, and Kore.
