WebThe Chandler wobble is the change in the spin of Earth on its axis. Think of the wobble you see in a toy top when it first starts spinning or slows down. Earth’s "poles" do not spin in a perfectly straight line. The location of the North geographic pole wanders in a small erratic circle-like path, called the "Chandler wobble."
