2. Precession
   This is the slow movement of the celestial poles tracing out large circles on the celestial sphere. It is caused by a slow wobble in the Earth's axis due to the gravitational effects of the Sun and Moon on the Earth's equatorial bulge. A reasonable analogy is that of a spinning top - As the top slow...

3. Precession
   Circular motion about the axis of rotation of a body; fixed with respect to the stars. The Earth is a giant gyroscope whose axis passes through the North and South Poles and this axis precesses with a period of 27,700 years.

    a change of longitude, measured in the frame of reference defined by the primary body and the stars, of a characteristic point in a satellite orbit, such as the ascending node NOTE 1 - Precession of the orbit of a satellite is caused by a perturbation of its orbital motion, due for instance to non-u...

16. Precession
    `Precession` is a change in the orientation of the rotation axis of a rotating body. It can be defined as a change in direction of the rotation axis in which the second Euler angle (nutation) is constant. In physics, there are two types of precession: torque-free and torque-induced. In astronomy, &q...

17. Precession
    (disambiguation) `Precession` refers to a specific change in the direction of the rotation axis of a rotating object, in which the second Euler angle (angle of nutation) is constant `Precession` may specifically mean: `Precession` can also refer to change in the direction of an axis other than an axis of rotation: See also :

18. Precession
    (mechanical) `Precession` is the process of a round part in a round hole rotating with respect to that hole because of clearance between them and a radial force on the part that changes direction. The direction of rotation of the inner part is opposite to the direction of rotation of the radi...
