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.
But Earth's axis tilt doesn't change either. What does change is Earth's orientation relative to the Sun. While Earth spins on its axis, it is also traveling around the Sun in orbital revolution. One full orbit around the sun is about 365 Earth days, or one year.ecause of Earth's spherical shape and axis tilt, incoming radiation is not absorbed evenly across the planet, and this distribution changes with the seasons. Earth's rotation is the cause for the differences in daytime and nighttime as it spins on its axis.
