All stars rotate and are therefore flattened by the centrifugal force. The faster the rotation, the more oblate the star becomes. Our Sun rotates with a period of 27 days and has a radius at the equator that is 10 km larger than at the poles; for the Earth this difference is 21 km.
R otation is when a planet or moon turns all the way around or spins on its axis one time. The axis of rotation is an imaginary line going from the north pole to the south pole. When a planet or moon travels once around an object this is considered a revolution.On Earth, a rotation is pretty short-it happens once a day!It is the rotation that makes the sun appear to come up in the morning and set at night. On Earth, a revolution is quite a bit longer-one year!hen a planet or moon travels once around an object this is considered a revolution. On Earth, a rotation is pretty short-it happens once a day!
