Is the sun bigger than the moon?

I have a bet with my brother who says the sun is way bigger and he's totally gonna lose because the sun and the moon are the same size and the moon sometimes even looks bigger. In the movie ET the moon is like totaly huge. The winner of the bet gets to punch the loser in the stomach with FULL FORCE hee hee even though my brother is like 4 times biger than me and 10 times stronger he's really gonna hurt when I sock him!!!
