Jupiter is the fastest-rotating planet in our solar system, it only takes at about 10 hours to complete its one rotation. The evidences for the fastest motion of Jupiter is it's gravity. Jupiter is the vacuum cleaner of planets or is having the highest gravity. The more the rotation the more the gravity. That's why Jupiter is having the highest rotational speed as it has the highest gravity.
Due to this we find the Jupiter is having the highest natural satellites. Also the asteroid belt is present between the Mars and Jupiter.
