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.
A revolution: The Earth revolves in an elliptical (oval) orbit around the Sun. This orbit is planetary; the Sun is a star, and a large object that orbits a star is known as a planet.
