The orbit of satellites experience this phenomenon with a frequency proportional to the radius to the negative seven halfs due to the quadrapole term in the Earth's gravitational field.  
The orbit of satellites experience this phenomenon with a frequency proportional to the radius to the negative seven halfs due to the quadrapole term in the Earth's gravitational field.  Since the Moon orbits the Earth at a slight angle to the Earth's orbit, a variation called nutation is imposed on this effect of the Equinoxes.  There are torque-free and torque-induced varieties of this phenomenon; the torque induced variety is sometimes known as the "gyroscopic" form. For 10 points, name this shift in the axis of a rotating body.
