Answer
$\color{blue} Requires$ : Summary for the theory that describes the formation of our solar system
Work Step by Step
We can describe this theory in a few statements:
1-The nebular theory states that the early solar system originated as a cloud of dust and gas about 5 billion years ago as a star gravitationally collapsed.
2-This rotating nebular cloud eventually contracted into a flattened, rotating disk.
3-The cloud cooled and heavier metallic and rocky material condensed and accreted into the inside
4- After cooling, the outer planets formed from residual gases and ices in the outer nebular cloud.
