Earth's eccentricity cycle
WebMay 9, 2024 · Every 405,000 years or so, the shape of the Earth's orbit shifts from almost perfectly circular to slightly elliptical, thanks to the complex interactions between Earth and other planets,... WebJan 16, 2024 · The Earth's eccentricity occurs in a cycle that has been well documented. Climatologists refer to this cycle as periodicity. The periodicity is 100,000 years—that is, the time necessary to change the orbit from a nearly circular one to a more elongated one.

Nudged by the gravitation of Jupiter, Mars, Venus and other planets, our world’s axial tilt and precession are always... WebMilankovitch cycles describe a set of different cyclical changes in the Earth's orbit around the sun and rotational axis. Whilst this is a simplification, there are three main cycles that respectively control changes in eccentricity of the Earth's orbit, the tilt/obliquity of the Earth's rotational axis, and the precession of the Earth's orbit.
