Why is the sun slow in the winter?

Why is the sun speedier in the winter? I think the winter snow  gets in the sun so it cools down  and I think that is how the sun gets slower. Or there could be a crack in the sun and tiny specks of white snow gets in the sun and burns the fire in the sun. The earth orbits the sun every 365 days. Some times we get direct light  and some times we get indirect light. The Earth and the moon also spin. The earth spins like a basketball on a finger. The atmosphere also stops earth from being too hot or too cold.
