      @Hollie Mae Yes! In about 5 billion years it will expand to a red giant and then after a final hurrah ejecting lots of gas into a planetary nebula, it will contract to become a small cold white dwarf which will cool until it has no energy to emit and then become a black dwarf – a dead star.

      All stars die, and the mass of the star determines how quickly it does – the biggest stars only last a few million years – our star will last about 8 billion from birth to death – we’re about halfway through it’s lifetime.

      As the others have said, eventually it will. Hopefully, though, by that time humans will have left Earth and be living on other planets around other stars, so it won’t matter if the Sun goes out!
