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 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 ...

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.

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 ...

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.

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: ...

This is essentially what's happening to Earth, what's known as "precession." In fact, our planet's tilt is making this circle over the course of 26,000 years, which is why the North Star, or ...

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.

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.

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. (Frits Hilgen) ...
