Final answer:
Our solar system probably formed from a cloud of gas and dust called a solar nebula that collapsed under its own gravity and formed a spinning disk. The central region of the disk became the sun, and the smaller particles clumped together to form the planets.
Step-by-step explanation:
The most widely accepted theory of how our solar system formed is the nebular hypothesis. According to this hypothesis, our solar system formed from a cloud of gas and dust called a solar nebula. As the nebula began to collapse under its own gravity, it started to spin and flatten into a spinning disk. The central region of the disk eventually became the sun, while the smaller particles in the disk clumped together to form planets, including the nine planets in our solar system.
