What are stars and how are they formed?

Answer 1

Stars come in different sizes. There are small, medium, and large stars, although small stars seem REALLY big already. The sun is a medium-sized star. Stars are big balls of gas covered with flames at a REALLY high temperature (look it up). Dense parts of molecular clouds collect into a ball of plasma to form a star. Stars grow bigger and bigger, and then they evolve into a red giant. And then later,
KABOOM!!!
The sun explodes with a very big explosion while it's a supernova, turning into either a black hole or a white dwarf.
That goes for the sun too, but just don't worry, because you'll only be able to experience the explosion if you have immortality!
