1590s, from Late Latin praecissionem (nominative praecissio) "a coming before," from past participle stem of Latin praecedere "to go before" (see precede). Originally used in refer [..]

The apparent shift of the celestial poles caused by a gradual wobble of the Earth's axis.

slow change in the direction of the axis of the Earth or another rotating body.

The wobble over thousands of years of the tilt of the Earths axis with respect to the plane of the solar system. [3]

n. The act of going forward.

The slow rotation of the axis of spin of the Earth around an axis perpendicular to the ecliptic plane. The rotation is clockwise as observed from the north celestial pole.

The motion that results from the application of a torque that tends to displace the axis of rotation of a rotating object.

The slow change in direction of the earth's axis due to the gravitational pull of the moon on the bulge at the earth's equator. The slow change in the axis causes the westward mo [..]

(n) the motion of a spinning body (as a top) in which it wobbles so that the axis of rotation sweeps out a cone(n) the act of preceding in time or order or rank (as in a ceremony)

 a complex motion excuted by a rotating body subjected to a torque tending to change its axis of rotation

See climatic precession.

Movement of a gyro in response to applied forces. Can be the cause of gyroscopic instrument errors.

A modern term, derived from the precession of the equinoxes and meaning a motion around a cone of the rotation axis of a spinning body.

The tendency of the Earth's axis to wobble in space over a period of 23,000 years. The Earth's precession is one of the factors that results in the planet receiving different amounts of sola [..]

Movement of axis of a free gyro when subjected to an angular force that is not coincident with plane of rotation. It results in direction and plane of spin taking up a position so that each particle i [..]

The comparatively slow torquing of the orbital planes of all satellites with respect to the Earth's axis, due to the bulge of the Earth at the equator which distorts the Earth's gravitationa [..]

Periodic change in the direction of an objects axis caused by the gravitational influence from another body.

A change in the direction of the axis of spin of a rotating body.
