Which is Hotter? ~updated~

I am going to have a competition called “Which is Hotter; Sun vs. Big Red Star?”

I have been reading about our sun and stars and I went to a planetarium with my Grandma. We learned a little bit about the universe, but I did not find out which type of star was hotter. I thought a competition would be a great way to learn. Next Saturday I will look up  the answer and see who was correct!

Here is what you do:

  1. Read the title.
  2. Think about your answer. Do not look up the answer!
  3. Post your answer as a comment.

Thank-you!

UPDATE

Everybody was right, the sun is hotter than a red star. Congratulations! Everybody who participated can now spend as much time with me as they want!

I looked up the answer using Google. I found the answer on Wikipedia, but Mom made me check another site too. Here is the link to Wikipedia if you want to read more: http://en.wikipedia.org/wiki/Stellar_classification

Ol’ Papa, I also learned that the stars are different colors because of how hot they are. The hottest stars are blue and the coolest stars are red.
