3. The Hertzsprung-Russell Diagram shows the three very different types of stars. The first type is called the Main Sequence which includes the sun. These stars are fueled by nuclear fusion, converting hydrogen into helium. The hotter they are, the brighter they become. They last for about five billion years. The second type include the supergiants. As they reach old age, they deplete their hydrogen supply. Their core contracts as their outer layers expand.
