Circular motion performed by a spinning object about a fixed line in space which is not its axis of rotation (spin)
The slow change in the direction of the axis of a spinning object, caused by some external influence
A modern term, derived from the precession of the equinoxes and meaning a motion around a cone of the rotation axis of a spinning body
The slow gyration of the earth's axis around the pole of the ecliptic, caused mainly by the gravitational pull of the sun and moon
Phenomenon associated with the action of a gyroscope or a spinning top and consisting of a comparatively slow rotation of the axis of rotation of a spinning body about a line intersecting the spin axis. It arises as a result of external torque acting on the body. One example of precession is the smooth, slow circling of a spinning top (the uneven wobbling is called nutation). Precession of the earth's axis of rotation is the reason that the positions of celestial bodies appear to drift systematically with the passage of time. See also precession of the equinoxes
The slow, smooth increase or decrease of an angle When used to describe the changing orientation or an orbit, one can imagine an ellipse (the orbit) spinning around a central point When used to describe a spinning body, it is the circular gyration of the body's rotation axis
The tendency of the Earth's axis to wobble in space over a period of 23,000 years The Earth's precession is one of the factors that results in the planet receiving different amounts of solar energy over extended periods of time
wobble in Earth's axis that, over a cyclical period of 23,000 years, influences the time at which the earth is closest to and farthest from the sun; ultimately, this affects the timing of the changes of the seasons on Earth
Circular motion about the axis of rotation of a body; fixed with respect to the stars The Earth is a giant gyroscope whose axis passes through the North and South Poles and this axis precesses with a period of 27,700 years
The comparatively slow torquing of the orbital planes of all satellites with respect to the Earth's axis, due to the bulge of the Earth at the equator which distorts the Earth's gravitational field Precession is manifest by the slow rotation of the line of nodes of the orbit (westward for inclinations less than 90 degrees and eastward for inclinations greater than 90 degrees)
Refers to two geometical systems which, oriented perpendicularly to each other, reveal a new system or geometric relationship
slow wobble of an object's rotation axis or an object's orbit The precession of the Earth's rotation axis is caused by the gravitational pulls of the Sun and the Moon on the Earth's equatorial bulge
the motion of a spinning body (as a top) in which it wobbles so that the axis of rotation sweeps out a cone
The motion that results from the application of a torque that tends to displace the axis of rotation of a rotating object
A slow but relatively uniform motion of the earth's rotational axis that causes changes in the coordinate systems used for mapping the sky The earth's axis of rotation does not always point in the same direction, due to gravitational tugs by the sun and moon (known as lunisolar precession) and by the major planets (known as planetary precession)
The apparent shift of the celestial poles caused by a gradual wobble of the Earth's axis
An isolated nuclear spin's state can be associated with a spatial direction using the Bloch sphere representation If the direction rotates around the -axis at a constant rate, we say that it precesses around the -axis The motion corresponds to that of a classical top experiencing a torque perpendicular to both the -axis and the spin axis For a nuclear spin, the torque can be caused by a magnetic field along the -axis
Precession refers to the wobbling effect that a rotating object has A top wobbles a little bit as it spins The earth also has a little wobble What we see as due north, where the North Star is, is slowly changing
the act of preceding in time or order or rank (as in a ceremony) the motion of a spinning body (as a top) in which it wobbles so that the axis of rotation sweeps out a cone
A modern term, derived from the precession of the equinoxes and applied to motion around a cone by the rotation axis of a spinning body
comparatively slow gyration of the axis of a spinning body so as to trace out a cone; caused by the application of a torque tending to change the direction of the rotation axis, and continuously directed at right angles to the plane of the torque The magnetic moment of a nucleus with spin will experience such a torque when inclined at an angle to the magnetic field, resulting in precession at the Larmor frequency A familiar example is the effect of gravity on the motion of a spinning top or gyroscope
The slow change in the direction of Earth's axis of rotation One cycle takes nearly 26,000 years
Due to the pole of the equator revolving around the pole of the ecliptic, the equinoctial point moves backward with relation to the constellations at the rate of approximately 50" per year It makes a complete revolution through the twelve constellations in the great cosmic year of 25,920 earthly years, or 2160 years to pass through one constellation There is disagreement among authorities as to the exact position of the vernal equinox (0° Aries) at present, but all are agreed that it is approaching the end of the Age of Pisces and entering the Age of Aquarius
a slow change in the direction of the Earth's axis of rotation caused by external forces; one cycle takes nearly 26,000 years
The slow westward shift of the equinoxes along the plane of the ecliptic, resulting from precession of the earth's axis of rotation, and causing the equinoxes to occur earlier each year
A slow westward shift of the equinoxes along the plane of the ecliptic, resulting from precession of the earth's axis of rotation, and causing the equinoxes to occur earlier each sidereal year. The precession of the equinoxes occurs at a rate of 50.27 seconds of arc a year; a complete precession requires 25,800 years. 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. This precession, a wobbling in the orientation of Earth's axis with a cycle of almost 26,000 years, is caused by the gravity of the Sun and the Moon acting on Earth's equatorial bulge. The planets also have a small influence on precession. Projecting Earth's axis onto the celestial sphere locates the northern and southern celestial poles. Precession makes these points trace out circles on the sky and also makes the celestial equator wobble, changing its points of intersection (equinoxes) with the ecliptic
