Although only incidental to the Bard’s canon, Earth’s precession is actually crucial to astronomers. We use a coordinate system on the sky that is very much like longitude and latitude.

The precession of the equinoxes refers to the precession of Earth's axis of rotation with respect to inertial space. The precession of the equinoxes is caused by the differential gravitational ...

Earth’s climate has never been static. ... ・Precession (21,000-year cycle): Earth wobbles on its axis, changing the timing of the seasons. These cycles interact in complex ways, ...

But Earth has a massive moon, which pulls on Earth's spin axis and drives it to precess faster. This slightly faster precession prevents it from experiencing spin orbit resonances.

Our Earth behaves much the same, and over time, its rotational axis traces a giant circle among the stars. Rarely does anyone other than astronomers ever think about precession since a full cycle ...

The alternations, interpreted as a signal of Earth's precession cycle, help us estimate the distance between Earth and the moon 2.46 billion years ago. (Image credit: ...
