Pasiphaë group
The Pasiphaë group is believed to have been formed when Jupiter captured an asteroid which broke up after a collision. The original asteroid was not disturbed heavily: the original body is calculated to have been 60 km in diameter, about the same size as Pasiphaë; Pasiphaë has 99% of the original body's mass. However, if Sinope belongs to the group, the amount is much smaller, 87%.
