Answer:
The movement is called revolution when a body travels around another body in space.
Explanation:
The movement is called revolution when a body travels around another body in space. It is different from rotation which is a phenomenon where a body revolves around its own axis. For example, we can assume the motion of earth as revolution when it travels around the sun and completes one complete revolution in one year, on the other hand when it moves around its own axis the day and night transformation happens. We can also take the example of moon which revolves around the earth and many other planets which revolve around the sun. So it is very easy to understand the concept of revolution.
