1 If you look up the word "solar" in your dictionary, you'll find its basic definition reads something like: "of the sun," or "relating to the sun." System is defined as: "a set of things or parts forming a whole." When you consider the meanings of these words, there is indication that the sun plays a major role among this group of celestial bodies we call the "solar system."
2 The sun is, in fact, at the center of this massive system. There are nine major planets and their satellites, asteroids, comets, dust and gases that are continually traveling around the sun. With a mass that is 750 times as great as that of all of the planets in the solar system combined, the sun has a strong gravitational pull that keeps the other objects in orbit around it.
3 As the planets revolve around the sun, the sun revolves around the center of the Milky Way Galaxy. The Milky Way, which has a circular shape, is made up of dust, gases, planets, and about 100 billion stars. The sun, planets, and other bodies and gases that make up our solar system are only a small speck in this huge galaxy!
