Star

Stars  are suns and the sun is a star. Stars only look small and faint because they are incredibly far away. The nearest star is Proxima Centauri and is just over light years away. That means Proxima Centauri is so far away that it takes light over  years to reach the Solar System from there. The other stars are even further away.

Some stars are hotter than the sun. Those stars look blue in the sky. Other stars are cooler than the sun. Tnhey lok red in the sky. Stars are incredibly hot and shine because nuclear reactions in their cores keep heating them. When the nuclear fuel is exhausted some stars blow themselves up to form supernovi. Other stars form black holes or white dwarf stars or pulsars. Astronomy is cool.
