Stars Meaning and Definition in Wikipedia
A star is a giant ball of very hot gas. That gas is called plasma. Stars are held together by gravity. They give out heat and light because they are so hot.
Stars are hot because of nuclear reactions happening inside them. Those reactions are called nuclear fusion. Nuclear fusion makes light and heat and makes bigger and bigger chemical elements. Stars have a lot of hydrogen. Nuclear fusion changes hydrogen into helium. When a star gets old, it starts to change the helium into other bigger chemical elements, like carbon and oxygen. Fusion makes a lot of energy. The energy makes the star very hot. The energy produced by stars moves (radiates) away from them. The energy leaves as light which we call electromagnetic radiation.
