The Sun is a yellow-dwarf star. And it's actually a fairly average star in age and in size! It has been shining for about five billion years. Compared to other stars, our Sun is rather ordinary; it appears to be so much bigger and brighter to us because it is millions of times closer than any other star. Stars the size of our sun have enough hydrogen to burn for about 10 billion years. Our sun already has used up half its fuel. In 5 billion years more, our sun will have converted its hydrogen to helium. It will grow larger but cooler, and it will become a red giant. It will be as big as the orbits of Earth or Mars. (Mercury and Venus, which are closer to the sun than Earth, will be burned up completely.) Earth will have a larger orbit than it does now, but the red-giant sun will still be hot enough to bake everything on Earth into brick. Our red-giant sun will begin to burn its helium atoms, and they will fuse into atoms of carbon. After many millions of years, the helium will be completely used up.
The sun will blow part of its carbon remains into space as a powerful wind. The remaining electrons will collapse into a white dwarf, a star as small as Earth but much heavier and brighter. As the white-dwarf sun cools, it will turn Earth into an icy globe. Since all this will take billions of years, we don't need to worry about the sun failing in our lifetime. There will be warmth and energy for ages to come.

STAR!
The Sun is the star of our solar system. A star is a massive, compact body of plasma in outer space that is held together by its own gravity and is sufficiently massive to sustain nuclear fusion in a very dense, hot core region.
The Earth and other matter (including other planets, asteroids, meteoroids, comets and dust) orbit the Sun.

Stars are suns of other solar systems. it is really interesting to read up on our own planets too. Did you know that Jupiter is almopst the size of a sun. It is like a solar system with in a solar system. Like you really want all of the information on the site but you can let him read it it is very interesting.
