The Formation of the Solar System out of the Primordial Nebula

The solar system contracted out of a rotating cloud of hydrogen and helium gas. The momentum of the rotation flattened the originally round cloud into a disk, somewhat the way a ball of pizza dough can be made flat by spinning it in the air. As it flattened, gaseous material condensed, then collected together to form more solid material.
