Our solar system is thought to have started with the birth of our sun, which formed from a cloud of interstellar dust and gas. this cloud condensed and eventually collapsed from its own gravitational pull. the heat and pressure built up, forming a protostar. eventually, nuclear fusion began. planets formed from remaining dust and gas orbiting the protostar.
this explanation best describes

the nebular theory
the big bang theory
the inflation theory
the condensation theory

The correct answer for: Our solar system is thought to have started with the birth of our Sun, which formed from a cloud of interstellar dust and gas. This cloud condensed and eventually collapsed from its own gravitational pull. The heat and pressure built up, forming a protostar. Eventually, nuclear fusion began. Planets formed from remaining dust and gas orbiting the protostar.

This explanation best describes . Is: 1.- The nebular theory.

Explanation:

To understand this answer we need to know the summaries of all of the theories. First, the theory of the big bang is a theory that speaks about the creation of the whole universe not only from our solar system so, but it is also discarded. Then, we have the inflation theory which also speaks about the universe and how it is expanding rapid and short periods considering its gravity. Then, we have the condensation theory which talks about how the planets have a certain force that makes them be attached to the sun into circular patterns, as well as explaining their composition. Finally, we have the nebular theory which not only talk about our solar system but the nature of all of the solar systems.
