    precession
    precession 1. The act or fact of preceding; precedence. 2. In astronomy: the slow, conical motion of the earth's axis of rotation, caused by the gravitational attraction of the sun and moon, and, to a smaller extent, of the planets, on the equatorial bulge of the earth. In certain contexts, 'prece...

    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 radia...

    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 ...

    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, "pr...

    Precession
    can refer to a slow change in the orientation of an object's axis of rotation. For the Earth, this is referred to as the precession of the equinoxes. Apsidal precession means a steady change in the orientation of an orbit, such as the precession in the orbit of Mercury that was explained by the the...

    precession
    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...

    precession
    a conical motion of the axis of rotation of a rotating body about a direction fixed in relation to the stars, due to the application of an external force NOTE - Precession of a rotating body should not be confused with precession of the orbit of a satellite.

    precession
    A slow, periodic conical motion of the rotation axis of a spinning body, most familiar in the wobbling of a toy top or gyroscope. Earth's axis precesses, once around every 25,800 years, as a result of it not being perpendicular to the ecliptic (the plane of Earth's orbit around the Sun). Being tippe...
