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 ...

Precession is the direction Earth's axis of rotation is pointed. (Image credit: NASA/JPL-Caltech) As Earth spins, its axis wobbles in a circle . This effect is called axial precession.

・Precession (21,000-year cycle): Earth wobbles on its axis, changing the timing of the seasons. These cycles interact in complex ways, sometimes reinforcing each other and at other times working ...

In other words, if our planet were a perfect sphere, there would be no precession. While a top or gyroscope might precess several times each second, a single precession of Earth’s axis takes ...

Axial precession causes Earth to make a full 360° turn on its axis every 25,771 years, while the apsidal precession leads to an additional 360° turn (in the same direction) ...

This visualization shows Earth’s axial precession, a wobble in the planet’s rotational axis with a period of about 26,000 years that is induced by tidal forces from the sun and moon.

Notably, a 1976 study found geological evidence showing that two of Earth's parameters — obliquity and precession, or changes in Earth's axial tilt and how the axis wobbles around itself ...

If it wasn’t for Pope Gregory XIII establishing our current Gregorian calendar, the 26,000-year cycle of Earth’s wobbling axis would eventually cause northern winter in June.

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.

Researchers suggest that two Earth-like exoplanets (Kepler-186f and 62f) have very stable axial tilts, much like the Earth, making it likely that each has regular seasons and a stable climate.

Earth's axis is currently tilted at a 23.5-degree angle away from vertical as it rotates around the ... the researchers plotted known changes in obliquity and precession over the past 800,000 years.
