The spinning cloud flattened like a disk and spread.

In the outer regions of the cloud, icy matter and gas formed the giant planets.

Gravity caused the cloud of gas and dust to spin.

Leftover debris formed asteroids, comets, and outer planets, like Pluto.

An explosion of a supernova led to a gravitational collapse of a dense cloud of gas and dust.

The cloud of gas and dust grew hot and created the Sun.

Near the center of the cloud, clumps formed rocky planets.
