Question: Will the sun ever go out?

Keywords:

  1. Yes, but not for a very long time. Eventually it will have no more hydrogen to “burn” in the giant nuclear explosion that keeps it going. It does have some alternatives, but they will not last forever either.
    As it burns out, it will expand until our Earth is INSIDE the Sun (melted of course).

  2. Every star (including the sun) will eventually run out of the nuclear fuel at its centre. Some stars are hot enough that they can fuse other atoms too, but the sun is not that hot (compared to other stars). So once it runs out of hydrogen, that’s it. Fortunately, that won’t happen for about 5 billion years.
