What Stars Do
Stars are made mostly of hydrogen and helium, and they shine because they burn these gases in a process called fusion. This is what gives them their energy and makes them light up the night sky.
What Planets Do
Planets are usually smaller than stars. They go around stars like Earth goes around the Sun. They can have moons, like how our Moon orbits Earth.
Examples
- Stars burn for millions of years, but planets don’t burn, just like how you can’t make your room light up by holding a ball.
