Pasiphae group

This diagram illustrates the largest irregular satellites of Jupiter. Among the Pasiphae group, Sinope and Pasiphae itself are labelled. An object's position on the horizontal axis indicates its distance from Jupiter. The vertical axis indicates its inclination. Eccentricity is indicated by yellow bars illustrating the object's maximum and minimum distances from Jupiter. Circles illustrate an object's size in comparison to the others.

The Pasiphae group is a group of retrograde irregular satellites of Jupiter that follow similar orbits to Pasiphae and are thought to have a common origin.

Their semi-major axes (distances from Jupiter) range between 22.6 and 24.3 million km (similar range as the Carme group), their inclinations between 141.5° and 157.3°, and their eccentricities between 0.22 and 0.44.

The members of the Pasiphae group are:[1]

The International Astronomical Union (IAU) reserves names ending in -e for all retrograde moons.
