  Hmm, not sure. I guess not! Good question.

  Oh good question! I guess if the sun was a lot less warmer it wouldn’t be generating as much energy from hydrogen fusion. Perhaps, if it was generating less energy from these reactions it would emit light at different frequencies so it could look a different colour perhaps but I’m not sure if it would be dimmer. That’s a cool query- does anyone else know?
