Stars shine because they burn fuel inside them, just like a fire burns wood. Imagine you have a giant ball of hot gas, that’s what a star is made of. Inside it, tiny particles called hydrogen join together to make helium, and this process releases energy in the form of light and heat. This is like how a match lights up when it burns, stars keep burning for millions of years because they always have fuel to burn.
Examples
- The Sun is a star, and it’s shining because it’s burning its own fuel inside it.
- Imagine a fire in the sky, that's what a star looks like when it shines.
