Astronomy: precession of earth - Washington State University

The physical cause of the precession is a torque (twisting) of the earth, caused mostly by the sun's and the moon's gravity pulling on the equatorial bulges of the earth. If earth were NOT spinning, the sun and moon would pull the earth so that the bulges were flat in the sun-earth orbital plane.

What causes precession or nutation in a spinning object?

So, the nutation is a cyclic energy conversion process: - there is a stage of giving in to the torque that is being exerted. - during that stage the torque is doing work and the kinetic energy of the spinning object increases, which goes to the precession rate.

This causes the celestial poles to describe ellipses, with a semimajor axis of 18.42" and a semiminor axis of 13.72". What that means is that the motion of the celestial poles around the normal to the ecliptic is not a perfect circle, but is a perturbed motion given by the sum of the precession motion plus the motion on the nutation ellipse.
