The Sun, the source of all lifeform in Earth

There are billions of stars in our universe but only one star dominates our solar system, the SUN. It is made of Hydrogen(H) and Helium(He). H and He are super heated up to millions of degrees. Inside the sun they behave like plasma. Our sun is a Yellow dwarf type star. It is called dwarf because compared to other star it is relatively small. But even though it is small as a star, yet in our solar system there is no bigger star than the sun. In fact it is the only star in our solar system. It is million miles across and one million earths can fit inside it.
