FAMILIES AND SCATTERING . ... An important observation on the orbital distribution of irregular satellites is that satellite families at Saturn, Uranus and Neptune are not well defined. At Jupiter one finds 3-4 reasonably compact retrograde families, corresponding to each of the previously known retrograde irregulars and one prograde family. ... That is contrary to the current doctrine that very little has happened to these irregular satellite families following their collisional formation. ...
