Earth perimeter at equator
WebDec 23, 2024 · If you multiply its height (481 ft.) by 43,200 you’re left with the polar radius of the Earth. This number, 43,200, is relevant because it represents the axial precession of the Earth or the way in which it wobbles on its axis. 43,200 is a multiple of 72, which is the number of years it takes for one degree of that wobble.
