when we observe the sun, we'll know that the position of black spots change every day. This is proof that the sun rotates, just like Earth. Earth rotates once in twenty-four hours or one day, but the sun rotates in a period of twenty-five days. it's just that, because the sun is a collection of gas, its rotation period of more or less different according to place. area around the equator spinning faster and vice versa, the part that is close to the rotational axis more slowly.
