What term refers to the movement of an object around another object?

The term that refers to the movement of an object around another object is "revolution." In the context of celestial bodies, revolution describes the path an object, such as a planet, takes as it moves around a star, such as the Earth orbiting the Sun. This movement is generally elliptical and is dictated by the gravitational forces between the two objects.

In this scenario, while "orbit" may seem similar because it describes the path taken during the revolution, it is more about the specific trajectory rather than the movement itself. "Rotation" refers to the spinning of an object around its own axis, which is different from moving around another object. "Centrifugation" is a process used to separate substances of different densities using a centrifuge, which is not related to the concept of movement around another object. Thus, "revolution" is the most accurate term to describe this type of movement.
