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. What … See more In astronomy, precession refers to any of several gravity-induced, slow and continuous changes in an astronomical body's rotational … See more • Media related to Precession at Wikimedia Commons • Explanation and derivation of formula for precession of a top • Precession and the Milankovich theory From Stargazers to Starships See more Torque-induced precession (gyroscopic precession) is the phenomenon in which the axis of a spinning object (e.g., a gyroscope) describes a cone in space when an external torque is applied to it.
