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. The planets have some gravitational influence ... astro.wsu.edu

What causes precession and other orbital changes
Joakim Lodin. Yup, the strength of gravity changes from about 9.78 m/s^2 at the equator to about 9.83 m/s^2 at the poles, mostly because of the spin of the earth and the resulting centrifugal force. Gravity also changes depending on how high up you are: the further you get from the center of mass the lower the gravity.
