Earth precession wobble
WebThis is due to a gyroscopic wobble of earth's spin axis that takes 26000 years to complete. In this wobble motion, the tilt of the earth stays roughly constant at 23.4 degrees but the orientation is always changing. One … WebPrecession 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, that body is said to be precessing about the second …
