I recently read that the Earth's axial tilt fluctuates between 22 degrees and 24 degrees. Can someone explain what causes the tilt to change? If I assume the Earth is perfectly spherical, gravitational forces cannot change the tilt.
So, is that the reason i.e. that the Earth is not perfectly round?
Or is there a different explanation for the tilt angle change?
Thank you
