Everything about Precession

Periodic change in the direction of a rotation axis

Precession is a change in the orientation of the rotational axis of a rotating body. 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. 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. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced. Wikipedia →

📖 Definitions

Noun Precedence.

Noun The wobbling motion of the axis of a spinning body when there is an external force acting on the axis.

Noun The slow gyration of the earth's axis around the pole of the ecliptic, caused mainly by the gravitational torque of the sun and moon.

Noun Any of several slow changes in an astronomical body's rotational or orbital parameters.
