Earth precession
Webtheory for orienting the Earth (precession, obliquity changes, and Greenwich Mean Sidereal Time) is considered in Sec. 8 and revised polynomial expressions are presented (Table 5). In addition to the theoretical corrections of this paper, these expressions use improved values of the obliquity, precession rate, masses, and ecliptic motion. WebThe associated precession period is.

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, … See more Torque-free precession implies that no external moment (torque) is applied to the body. In torque-free precession, the angular momentum is a constant, but the angular velocity vector changes orientation with time.
