Solar System Formation of the Solar System

Many scientists believed that the solar system was formed when in space a cloud of gas and dust was disturbed, by the explosion of a close by star known as a supernova. This explosion made waves in space which compressed the cloud of gas and dust. The cloud starts to collapse after getting pressed, as gravity together pulled the gas and dust, and formed a solar nebula. Thus, the cloud began to spin as it collapsed (UCAR).

Finally, as the cloud grew more hot and dense in the center, surrounded by a disk of gas and dust, which was hot in the center and cooler at the edges. And as the disk became thinner and thinner, particles...

The picture below shows small planetestimals forming a thin disk and orbiting the new Sun (UCAR).
Now near the center of the cloud, where planets like Earth formed, materials that were only rocky could stand the great heat. On the other hand, icy matter was settled in the outer regions of the disk along with rocky material, forming giant planets such as…
