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, that body is said to be precessing about the second axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free … WebOct 16, 2024 · Axial precession causes Earth to make a full 360° turn on its axis every 25,771 years, while the apsidal precession leads to an additional 360° turn (in the same … WebPrecession—the change in orientation of the Earth's rotational axis—alters the orientation of the Earth with respect to perihelion and aphelion.
