Our solar system began as a large cloud of gases and dust in the universe. There was a disturbance, likely the explosion of a star, that caused the cloud to collapse inwards towards its center.

What is the next most logical step in the formation of our solar system?

• Gas giants formed the 4 outer planets

• Rocky planets formed closer to the sun

• A flat disk forms

• Dust and gas collected into denser regions, and the cloud begins to spin
