Question

What is the difference between nutation and barycenter?

Answer 1

Generally speaking, precession is believed to occur as a result of the gravitational forces exerted by the sun and moon as they revolve around the earth. When an object revolves, its axis of rotation exhibits a nodding or swish motion. There is a wobble in the movement of precession. This phenomenon is caused by the gravitational pull exerted by one body upon another, resulting in nutation.

Hope this helps :)
