I remember an analogy with a child's spinning top, that does not rotate in a fixed axis but the axis makes a precessional movement.
But the spinning top is sitting on something, it's getting a force from below that's not aligned with its weight, so this force has a torque, etc etc (can't continue cause I don't really know how to )
But the Earth is not like this, there's no force from the bottom. Why does it have a precession then?
Would there be no precession without the moon?
