The precession of the equinoxes is caused by the gravitational forces of the Sun and the Moon, and to a lesser extent other bodies, on the Earth. It was first explained by Sir Isaac Newton. Axial precession is similar to the precession of a spinning top. In both cases, the applied force is due to gravity. For a spinning top, … See more In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis.

Because of the slow change in our orientation to the stars, the position of the Sun on the first the day of spring (the vernal equinox) slowly shifts westward around the sky, which also moves it around our calendar. That is why we refer to the effect as the precession of the equinox.
