The axis of Earth makes a 23.5° angle with a direction perpendicular to the plane of Earth’s orbit. As shown in, this axis precesses, making one complete
rotation in 25,780 y.If this torque were created by a single force (it is not)
acting at the most effective point on the equator, what would
its magnitude be?
Magnitude of the force
Here, L is the angular momentum of Earth and R is its radius.
