Summary

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.
