axis of precession
21precession — noun 1》 Physics the slow movement of the axis of a spinning body around another axis. 2》 Astronomy the slow retrograde motion of the equinoctial points along the ecliptic, resulting in the earlier occurrence of equinoxes each year. Derivatives… …
22precession — noun Etymology: New Latin praecession , praecessio, from Medieval Latin, act of preceding, from Latin praecedere to precede Date: 1879 a comparatively slow gyration of the rotation axis of a spinning body about another line intersecting it so as… …
23Apsidal precession — This article is about rotation of the orbit of a celestial body. For precession of the rotational axis, see precession of the equator. For change in orbital inclination, see precession of the ecliptic. In celestial mechanics, perihelion… …
24equinoxes, precession of the — Motion of the points where the Sun crosses the celestial equator, caused by precession of Earth s axis. Hipparchus noticed that the stars positions were shifted consistently from earlier measures, indicating that Earth, not the stars, was moving …
25Nodal precession — is the precession of an orbital plane around the rotation axis of an astronomical body such as the Earth. This precession is due to the non spherical nature of a spinning body which creates a non spherical gravitational field. Around a spherical… …
26Lunar precession — Unreferenced|date=May 2007There are two important precessional motions in the Orbit of the Moon.The long axis (line of the apsides: perigee and apogee) of the moon s elliptical orbit precesses about once in just under 9 years. It is caused by the …
27Lense-Thirring precession — is a general relativistic correction to the precession of a gyroscope near a large rotating mass such as the Earth. Before we can calculate this we want to find the Magnetic Field. The Magnetic Field in the equatorial plane of a rotating… …

29Rotation around a fixed axis — Rotational motion can occur around more than one axis at once, and can involve phenomena such as wobbling and precession. Rotation around a fixed axis is a special case of rotational motion, which does not involve those phenomena. The kinematics… …
30Larmor precession — In physics, Larmor precession (named after Joseph Larmor) refers to the precession of the magnetic moments of electrons, atomic nuclei, and atoms about an external magnetic field. The magnetic field exerts a torque on the magnetic… …
