A star is an extremely hot and large ball composed of plasma. Most stars get their light and heat energy from fusing Hydrogen into Helium. Other stars get energy from fusing heavier elements.

Stars range from red dwarfs that if they had only a little less mass they'd be a brown dwarf to supergiant stars with masses over 100 M that's about to go supernova in only a few thousand years.

Stars come in 4 main types - forming stars, main-sequence stars, giant stars, and dead stars. Forming stars are stars that just formed from a nebula or a gas cloud. Main-sequence stars are normal, shining stars. Giant stars are stars that are near the end of their lifespan and has its size and luminosity greatly increased while losing mass. A dead star is a star that has ended its lifespan - there are white dwarfs and neutron stars. Stellar black holes are also remnants of dead stars, but aren't stars.
