pre·ces·sion

 (prē-sĕsh′ən)
n.
1. The act or state of preceding; precedence.
2. Physics The motion of the axis of a spinning body, such as the wobble of a spinning top, when there is an external force acting on the axis.
3. Astronomy
a. Precession of the equinoxes.
b. A slow gyration of the earth's rotational axis around the pole of the ecliptic, caused by the gravitational pull of the sun, moon, and other planets on the earth's equatorial bulge.

[Late Latin praecessiō, praecessiōn-, from Latin praecessus, past participle of praecēdere, to go before; see precede.]

pre•ces•sion

(priˈsɛʃ ən)

n.
1. the act or fact of preceding; precedence.
2. the movement of the axis of rotation of a spinning body around another axis, outside the body and at an angle to it: an effect exhibited by a spinning top or gyroscope.
3. the slow, conical motion of the earth's axis of rotation caused by forces exerted on the earth by the sun and moon and responsible for the precession of the equinoxes.
[1300–50; < Late Latin praecessiō a going before, advance, derivative (with -tiō -tion) of praecēdere to precede]

pre·ces·sion

(prē-sĕsh′ən)
1. The motion of the axis of a spinning body, such as the wobbling of a spinning top, that arises when an external force acts on the axis.
2. The motion of this kind made by the Earth's axis, caused mainly by the gravitational pull of the sun, moon, and other planets. ♦ The precession of the equinoxes is the slow westward shift of the autumnal and vernal equinoxes along the ecliptic, resulting from precession of the Earth's axis. A complete precession of the equinoxes takes 25,800 years.
