Question

understand: the solar system
which statement best describes how our solar system was formed?
choose 1 answer:
a a dying star exploded, leaving behind a smaller star as well as many planets and moons.
b a cloud of gas and dust was pulled together by gravity, forming a star, planets, and moons.
c an asteroid collided with a star, causing the asteroid to break apart into planets and moons.

Explanation:

The most widely accepted scientific model for solar system formation is the nebular hypothesis, which states that our solar system formed from a rotating cloud of gas and dust (a solar nebula) that collapsed under its own gravity. Over time, the central mass became the Sun, while the remaining material clumped together to form planets, moons, and other solar system bodies. Option A describes a supernova remnant scenario which is not the main formation mechanism for our solar system, and Option C describes an event that does not align with the established formation process.

Answer:

B. A cloud of gas and dust was pulled together by gravity, forming a star, planets, and moons.
