Earth precession wobble
In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis. In the absence of precession, the astronomical body's orbit would show axial parallelism. In particular, axial precession can refer to the gradual shift in the orientation of Earth's axis of rotation in a cycle of approximately 26,000 years. … WebOct 14, 2008 · The non-uniform gravitational force of the Sun and the Moon will pull on this bulge and causes the Earth to wobble as it spin around it axis, just like a spinning top …

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 …
WebThat is, there is no such thing as nutation without gyroscopic precession. Earth wobble The Earth's spinning motion is very complicated. There is a torque from the Sun and a torque from the Moon, and the Moon's orbital plane is at an angle with the Earth orbit around the Sun.
