11 Formation of the Solar System A slowly rotating cloud of gas and dust begins to contract. A central condensation forms as the cloud flattens and spins more rapidly. Rougly100 thousand years later, a glowing “protosun” has formed in its center with a protoplanetary disk (proplyd) of gas and dust.
