Why is the sun a sun star?

Answer 1

Because we call giant balls of very hot gas, out in space, "stars" - and that's what the Sun is. People have named all of the stars they can see, not just our own.

Answer 2

It is the same as many of the other stars that we see, except that it is much nearer to us, so it seems larger and brighter.

Answer 3

It shares the same characteristics as a star. So they call it a star :v
