Earth wobble precession
WebJan 22, 2024 · Earth's precession is a large wobble (the entire axis or 22-24 degrees, or about 5,000 km), over 26,000 years. Chandler wobble is a small wobble, 30 feet over a period of 433 days. The Himalayas, for example, are irrelevant compared to Earth's equatorial bulge in terms of mass and gravitational influence.

Earth wobble The Earth's spinning motion is very complicated. There is a torque from the Sun and a torque from the Moon, and the Moon's orbital plane is at an angle with the Earth orbit around the Sun. Probably those influences play a role in the Earth wobble.
