WebFeb 20, 2024 · As Earth spins on its axis it wobbles slightly, similar to when a spinning top slows down. This wobble is called precession, and has an affect on seasonal extremes. (Image credit: NASA) WebAug 3, 2024 · The Chandler Wobble is one of the main components of the motion of the Earth's rotation axis relative to the Earth's surface, also called Polar Motion, according to a study published in the journal Earth, Planets and Space. A Chandler Wobble phase jump of about 180 degrees occurred in the 1920s.
