Precession Definition from Encyclopedia Dictionaries & Glossaries
English Wikipedia - The Free Encyclopedia
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 and torque-induced.

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 solar energy over extended periods of time.

Glossary of Astrological Terms
Due to the pole of the equator revolving around the pole of the ecliptic, the equinoctial point moves backward with relation to the constellations at the rate of approximately 50" per year. It makes a complete revolution through the twelve constellations in the great cosmic year of 25,920 earthly years, or 2160 years to pass through one constellation. There is disagreement among authorities as to the exact position of the vernal equinox (0° Aries) at present, but all are agreed that it is approaching the end of the Age of Pisces and entering the Age of Aquarius.
