Corotation refers to the synchronized rotation of two celestial bodies around a common center of mass. Some synonyms for corotation include co-rotation, synchronous rotation, and synchronous orbit. Additionally, other terms related to corotation include tidal locking, which refers to the gravitational forces that cause a natural body to rotate at the same rate as its orbit around a larger body, and geosynchronous orbit, which refers to an orbit in which a satellite completes one orbit around the Earth in the same amount of time as the Earth's rotation. These concepts are all closely related to corotation and play an important role in astronomy and planetary science.
