Title: Is there a large planet out beyond Pluto?
Post by: Peter Conway on 30/11/2009 12:30:10

Peter Conway asked the Naked Scientists:
   
Around the time that Pluto was declared not to be a planet, there was a report that a new large planet had provisionally been discovered beyond the orbit of Neptune, but I've heard nothing more about it, was it confirmed?

And how many planets do we how have 8, 9 or 10?

What do you think?
