This was because of Earth’s shift on its axis, or precession, which was corrected by an AI algorithm. This catalog predates the second oldest chart—compiled by ancient Greek astronomer ...

Rarely does anyone other than astronomers ever think about precession since a full cycle takes 25,800 years to complete. For most of modern history, the northern pole of our Earth’s axis has ...

The findings highlight the roles of precession, obliquity, and eccentricity – factors influencing the tilt and movement of Earth's axis, and the shape of Earth's orbit around the Sun – in ...

Earth's tilt, or axial precession, is influenced by the distribution of mass (in this case water) across the planet. The melting of glaciers and polar ice sheets from Greenland and Antarctica ...

A new study indicates the collision of Theia and the Earth about 4.5 billions years ago might have created more than one moon ...

The study of our Moon suggests that Earth once had not one but many tiny moons that vanished over a course of billions of years ...

Nodal precession means that particles in orbit around the Earth-Moon system slowly ‘precess’ (a slow, continuous change in a body’s orbital parameters) around the angular moment vector.

This precession causes the axis of Earth to describe a circle having a 23.4 degree radius relative to a fixed point in space over about 26,000 years, a slow wobble reminiscent of the axis of a ...

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.

This slightly faster precession prevents it from experiencing spin orbit resonances. So, the Moon stabilizes Earth’s obliquity, and Earth doesn’t wobble on its axis as much as Mars does.

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.
