There are four points of gear mesh in a standard diff. and the only time they turn is during a turn or when one wheel slips. There is no planet gear.

Misinterpreted your earlier post
And for whatever reason, my textbooks call what most call a pinion gear (on a diff) a planet gear (sorry for that confusion).... It calls the input gear (that meshes with the ring gear) the pinion gear (it is, small gear driving a big one). I said at least three because only 1 planet/pinion gear is required - having a second is good for reliability. And technically - including the ring gear mesh - there's 6 mesh points or a diff with 2 planet/pinion gears (each as two meshes with the side gears. /end textbook dump
