The sun is a ball of gas and does not move uniformly in the rotation around itself.
equator rotates faster than the poles. A full circle to the equator in 25 days (at a speed of 2 kilometers per second) and the poles in 34 days.
The sun's rotation on itself due to the revolution motion of the planets and asteroids, that motion that all solar system bodies perform at different distances, just turning around the sun.
intrippa Another thing is to think that the sun is 8 light minutes from us. It means that the light emitting Impega more than eight minutes to reach the ground. It means that if we do-horns - to be extinguished suddenly, we realize it after 8 minutes (nice consolation). And we realize it by seeing black center (which is the part closest to us) to the ends.
