In astronomy, what is the difference between rotation and revolution?

Answer 1

In astronomical parlance, period of revolution is the period for going around completely once through #360^o#. It is implicit that the period is for one complete rotation.

Although "complete rotation/revolution" is, in my opinion, implicit in the word "revolution," I don't want to focus on this as a general rule; nonetheless, I believe that this is a useful convention for distinguishing between rotation and revolution.

Rotation refers to the spinning motion of an object around its own axis. Revolution, on the other hand, refers to the orbital motion of an object around another object. In astronomy, rotation is typically used to describe the spinning of planets, stars, or other celestial bodies on their axes, while revolution describes their orbit around a central body, such as a star or a planet around a star.
