What (who) is precession$63104$ - definition

PERIODIC CHANGE IN THE DIRECTION OF A ROTATION AXIS

Gyroscopic precession; Precess; Precessing; Geometric precession; Torque-induced precession; Torque-free precession; Equinoctial precession; Free precession; Lunisolar Precession; Gyroscopic Precession; Discovery of precession; Precession of the earth; Precession of the Earth; Precession of Perihelion; Precession of the axis; Free Precession; Astronomical precession; Planetary Precession; Planetary precession; Procession of the equinox; Stellar precession; General precession; General precession in longitude; Precession (astronomy); Precessed; Percession

Apsidal precession

PRECESSION (ROTATION) OF THE ORBIT OF A CELESTIAL BODY

Perihelion precession; Precession of perihelion; Anomalistic precession; Apsidal period

In celestial mechanics, apsidal precession (or apsidal advance) is the precession (gradual rotation) of the line connecting the apsides (line of apsides) of an astronomical body's orbit. The apsides are the orbital points closest (periapsis) and farthest (apoapsis) from its primary body.

Axial precession

GRAVITY-INDUCED, SLOW, AND CONTINUOUS CHANGE IN THE ORIENTATION OF AN ASTRONOMICAL BODY'S ROTATIONAL AXIS

Precession of the Equinoxes; Lunisolar precession; Equinoctial Precession; Precession of the equinoxes; Precession of equinoxes; Precession of the equinox; Procession of the equinoxes; Precession of the equator; Precession of the ecliptic; Equinox precession; Precession of the Earth's axis; Axial precession (astronomy); Precession Of the Equinoxes; Procession of the equinoces; Precession of the earth's axis

In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis. In particular, it can refer to the gradual shift in the orientation of Earth's axis of rotation in a cycle of approximately 26,000 years.

precession

¦ 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.

Wikipedia

Precession

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, that body is said to be precessing about the second axis. A motion in which the second Euler angle changes is called nutation. 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. An important example is the steady change in the orientation of the axis of rotation of the Earth, known as the precession of the equinoxes.
