Stars all seem to be made up of the same elements that are found on Earth, even though they can be different sizes, temperatures, and ages. Our Sun is an average-size star, maybe a little smaller than most stars. Stars the size of our Sun are known as Dwarf Stars. The largest stars can be 10 times larger across then the Sun. These are called Giant or SuperGiant stars. The very smallest stars are not much bigger than the planet Jupiter. They can all be different colors. Their color depends on their temperature, how hot they are. The coolest stars are nearly 500 degrees, while the hottest stars can reach 90,000 degrees. Cool stars appear red, and hot stars look bluish-white
SO.... Giants and Supergiants are larger than the sun. Dwarf stars are the same size as our sun. Red are stars are cooler than our sun. Bluish-white stars are hotter than our sun.
