How the Solar System may have formed from a spinning cloud
Scientists think that the solar system formed out of a cloud of hydrogen and helium molecules, which was spinning.
Because the cloud was spinning, it flattened into a frisbee shape, just like a ball of pizza dough becomes flat when a chef spins it in the air. The planets and the sun started to form after the cloud became a flat disc.
