      Not really sure to be honest, not my area of work. I know that stars (which is what Suns are) change in size depending on where they are in their ‘life’. White dwarfs for example weigh the same as our Sun, but are only the size of Earth, so are super heavy.

      Check out this website:

      There are some big ones out there!

      Stars can’t go any bigger than about 32,000 times the mass of our own sun, this is because they literally shine so bright they blow away any more stuff that tries to fall onto them.

      Still, 32,000 times our own sun is pretty huge.

      Oooh, I’m not sure either. Niall and James’s answers look pretty good to me, I don’t know much about space so it’s always good to learn something new!
