Can You Explain Precession?

Precession, 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. The smooth, slow circling of a spinning top is precession, the uneven wobbling is nutation

nutation
Nutation occurs because the forces are not constant, and vary as the Earth revolves around the Sun, and the Moon revolves around the Earth. ... This causes the orientation of the Earth's axis to vary over the same period, with the true position of the celestial poles describing a small ellipse around their mean position.

What is precession with example?

Precession is a change in the orientation of the rotational axis of a rotating body. ... 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.

What is precession of the Earth?

Precession – As Earth rotates, it wobbles slightly upon its axis, like a slightly off-center spinning toy top. This wobble is due to tidal forces caused by the gravitational influences of the Sun and Moon that cause Earth to bulge at the equator, affecting its rotation. ... There's also apsidal precession.
