Jupiter, Uranus, ko Neptune, te atu aorangi nui i roto i te Solar System, e hoki oblate engari ki te whānuitanga iti. Ko te huinga o te bulge me te auau hurihanga tikanga e te tōtika i runga i te mata taumaha i te equator, 8.96 m / s2, ko 74% e te i nga pou, me te he raro atu i te taumaha o te mata o te whenua. Heoi, ko te rerenga equatorial katoa o Saturn he 36 km / s? ko reira he papatahi i runga i ona pou, me bulges i tona equator.
