Piece of trivia: The "Geographic pole" actually wanders a bit, probably mostly due to displacements of the mass of oceans and the atmosphere. I think it's on the order of about 100 meters or so. Presumably, this has to be accounted for in the calculations used by GPS receivers. https://en.wikipedia.org/wiki/True_polar_wander
This doesn't have anything to do with the movement of the magnetic poles, BTW.

is there place on earth where the sun doesn't rise from near east?
counterexample will be near the poles. there are two kinds of poles: geographic pole and magnetic pole. it appears to depend how they are placed: the middle of the line between them is a good candidate -- in this case exchanging them will swap directions.
Humans generally first defined "East" by magic magnetism voodoo, and generally the Sun rising "over there" in nomadic capabilities regardless, irrespective of trivial degenerate cases in modern science. A definition unlikely to change geophysically, till well beyond first voyages to the stars, thus compelling new contextually relavant astronomical definitions upon humanity at that time. https://wikipedia.org/wiki/Geomagnetic_reversal#Effects_on_biosphere https://wikipedia.org/wiki/Hominidae https://wikipedia.org/wiki/Magnetometer https://wikipedia.org/wiki/Future_of_Earth https://wikipedia.org/wiki/Global_catastrophic_risk https://wikipedia.org/wiki/Earth_Overshoot_Day https://wikipedia.org/wiki/Natural_resource Getting off the rock asap is of profound importance.
