What are Stars?

Stars are giant balls of gas in space. The stars are very hot! They can be up to 800,000 degrees Fahrenheit! Our own Sun is also a star. It supplies us with light and heat.

How do Stars Get So Hot?

This is how stars get very hot. A star is filled with gases called Hydrogen and Helium. The star has a lot of gravity, so the star smashes the Hydrogen molecules together to create Helium! The molecules in the Hydrogen actually fuse together to make a new gas called Helium. This process is how the star radiates out heat, light, and charged particles.
