Answer 1

The solar system consists of the Sun, planets, moons, asteroids, comets, and dust. Most of these objects formed together with the Sun about 4.5 billion years ago.

Step-by-step explanation:

The solar system consists of the Sun and many smaller objects: the planets, their moons and rings, and such "debris" as asteroids, comets, and dust. Most of these objects formed together with the Sun about 4.5 billion years ago. They represent clumps of material that condensed from an enormous cloud of gas and dust.The central part of this cloud became the Sun, and a small fraction of the material in the outer parts eventually formed the other objects.
