How are some stars so much larger than the Sun?
« on: 08/09/2011 12:01:02 »
Jacques Mulder asked the Naked Scientists:
   Hi newbielink:http://www.thenakedscientists.com/HTML/podcasts/ [nonactive].

Here the question:
We know some stars are big and some stars are small and gravity (and heat) is needed for nuclear fusion. How is it then that some stars like betelgeuse are so much larger than our own sun?

Regards

Jacques Mulder from South Africa
What do you think?
