Their semi-major axes (distances from Jupiter) range between 22.8 and 24.1 million km (the same range as the Carme group), their inclinations between 144.5° and 158.3°, and their eccentricities between 0.25 and 0.43.
Core members of the group include (from the largest to the smallest):
The International Astronomical Union (IAU) reserves names ending in -e for all retrograde moons, including this group's members.
Unlike the Carme and Ananke groups, the theory of a single impact origin for the Pasiphaë group is not accepted by all studies. This is because the Pasiphaë group, while similar in semi-major axis is more widely dispersed in inclination 1 . However, Secular resonances, known for both Pasiphae and Sinope, could shape the orbits and provide the explanation for the post-collision dispersal of the orbital elements. Alternatively, Sinope might be not a part of the remnants of the same collision and captured independently instead.
