Jupiter's Moons

Pasiphae Group

The Pasiphae Group of retrograde, irregular moons comprises eleven named moons.  All these moons orbit Jupiter at average distances between 22.8 and 24.1 million km.  The orbits are highly eccentric.  It is possible that the Ananke group formed after a captured asteroid broke up as a result of a low velocity collision, but Sinope is so large compared to Pasiphae itself, that this theory is not universally accepted. The orbits and inclinations of the various moons are very similar, but color measurements are not at all conclusive.
