The cycles include changes in Earth's axial tilt every 41,000 years, shifts in the orbit's shape over 100,000 years, and the precession or wobble of Earth's axis every 23,000 years.

How Earth's 26,000-Year Axial Precession Shifts the North Star Over Time. As per NASA, gravitational forces from the sun and moon affect the rotation of Earth; these produce a bulge at the equator and ...

Later observations written into the catalog showed inconsistencies with Shi’s findings. This was because of Earth’s shift on its axis, or precession, which was corrected by an AI algorithm.

Ancient Chinese astronomer Shi Shen’s star catalog, known as The Star Manual of Master Shi, is now considered the oldest star chart in the world. Later observations written into the catalog showed ...

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 ...

But due the slow wobble of Earth's axis or axial precession, PAGASA said this point is now located in the constellation Pisces. “The March Equinox marks the start of spring in the Northern Hemisphere.

The subtle changes in orbit (eccentricity), the planet’s inclination compared to the orbit (obliquity), and the change in the direction of Earth’s rotational axis (precession) were possible ...

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.
