Rotation period (astronomy)

In astronomy, the rotation period of a celestial body refers to the time it takes for that body to complete one full rotation around its own axis. This period varies widely among different celestial objects, including planets, moons, and stars. For example: - **Earth** has a rotation period of about 24 hours, which defines our day. - **Jupiter** has a much shorter rotation period of about 10 hours, making it the fastest rotating planet in our Solar System.
