Mar 19, 2017 at 7:27 comment added JDługosz @L.Dutch pulling on the oblate equator or other off-center mass will cause the axis to precess. Multi-body interactions do cause the axis to wander over the span of billions of years — our large moon prevents that on Earth.
Mar 19, 2017 at 7:25 comment added JDługosz The planet’s axis will move around on geologic time scales, not sudden frequent changes! A situation where another planet passes close on a regular basis will quickly modify the orbits, not the spin axis.
