Question

Which explanation of the solar system best fits the observations of the planets and how they orbit the sun?

Answer 1

Answer: C. The sun and planets formed from a collapsing spinning cloud of gas and dust.

Explanation:

The entire solar system was formed from solar nebula. A nebula is a cloud of dust and gases. When this cloud spins and contracts, a protostar is formed. The temperature rises and nuclear fusion kicks in forming a star. The rest of the matter forms planets and other celestial bodies of the star system. Similarly, the Sun was formed in solar nebula from collapsing of spinning cloud of dust and gas.

Answer 2

You're right, Answer C

The dust and gas accumulate to form a solar nebula, which later on creates the star and the planets.
