Nutation of earth

Webnutation, in astronomy, a small irregularity in the precession of the equinoxes. Precession is the slow, toplike wobbling of the spinning Earth … Precession and nutation are caused principally by the gravitational forces of the Moon and Sun acting upon the non-spherical figure of the Earth. Precession is the effect of these forces averaged over a very long period of time, and a time-varying moment of inertia (If an object is asymmetric about its principal axis of rotation, the moment of inertia with respect to each coordinate direction will change with time, while preserving angular momentum), and has a timescale of about 26,00…

WebNutation definition, an act or instance of nodding one's head, especially involuntarily or spasmodically. See more. The nutation of a planet occurs because the gravitational effects of other bodies cause the speed of its axial precession to vary over time, so that the speed is not constant. English astronomer James Bradley discovered the nutation of Earth's axis in 1728. Earth Nutation subtly changes the axial tilt of Earth … Meer weergeven Nutation (from Latin nūtātiō 'nodding, swaying') is a rocking, swaying, or nodding motion in the axis of rotation of a largely axially symmetric object, such as a gyroscope, planet, or bullet in flight, or as an intended … Meer weergeven • Libration • Teetotum Meer weergeven If a top is set at a tilt on a horizontal surface and spun rapidly, its rotational axis starts precessing about the vertical.

In physics, there are two types of precession: torque -free and torque-induced. In astronomy, precession refers to any of several slow changes in an astronomical body's rotational or orbital parameters.
