Earth precession rate
WebApr 12, 2024 · The first equation in Wikipedia's Nodal precession for the rate of precession ω p: ω p = − 3 2 R E 2 ( a ( 1 − ϵ 2)) 2 J 2 ω cos ( i) depends on the parameters of the orbit ( a, ϵ, ω, i) and the Earth's equatorial radius R E and its J 2 term. Let's use 6378137 meters for R E (from this answer) and 1.0826E-03 for J 2 (from this answer ). WebThe precession of the perihelion* and aphelion in the ecliptic plane is caused for the most part by earth's gravitational interactions with Jupiter and Saturn. It is possible that the effects of general relativity have a small impact as well. ( 1 vote) Steven Primeiro 9 years ago

The Moon's effect is actually larger, but these numbers are very sensitive to the values you use. ... The RATE at which it moves out of this position would determine the rate of axial precession. The time it takes for the ...
The precession of the Earth's axis has a number of observable effects. First, the positions of the south and north celestial poles appear to move in circles against the space-fixed backdrop of stars, completing one circuit in approximately 26,000 years. Thus, while today the star Polaris lies approximately at the north celestial pole, this will change over time, and other stars will become the "north star". In approximately 3,200 years, the star Gamma Cephei in the Cepheus constellat… WebEarth's Rotation. The Earth rotates on its axis relative to the sun every 24.0 hours mean solar time, with an inclination of 23.45 degrees from the plane of its orbit around the sun. Mean solar time represents an average of the variations caused by Earth's non-circular orbit. Its rotation relative to "fixed" stars (sidereal time) is 3 minutes ...

WebMar 29, 2024 · Such a motion is called precession and consists of a cyclic wobbling in the orientation of Earth’s axis of rotation with a period of 25,772 years. Precession was the third-discovered motion of Earth, after the far more …
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, if the axis of rotation of a body is itself rotating about a second axis, … See more Torque-free precession implies that no external moment (torque) is applied to the body. In torque-free precession, the angular momentum is a constant, but the angular velocity vector changes orientation with time.
