Your question contains a misconception. While celestial bodies rotate on their own axis, the term "rotation" is not typically applied to planets. Rotation is more commonly used to describe the spinning of a planet or other object around its own axis, resulting in the alternation of day and night. The time taken for one complete rotation varies for each planet. For instance, Earth rotates on its axis approximately every 24 hours, giving us the experience of a day. Other planets have different rotation periods; for example, Venus takes about 243 Earth days to complete one rotation, while Jupiter rotates very quickly, completing one rotation in about 10 hours.
