What is a star?

What are stars made of?

Stars are made up mostly of hydrogen and helium. Stars get so hot by burning hydrogen and helium in a process called a nuclear fusion. That's why stars are bright and high temperatures.

What types of stars are there?

There are dwarfs, giants, and neutrons. The dwarf stars are the smaller stars. The colors of dwarf stars are red, yellow, brown, and white. The giants may be the the main sequence like a blue giant, or stars that are expanding like a red giants. A neutron star is created from the collapse of a giant star.
