The Hubble Space Telescope has once again proven to be invaluable in discovering things about our solar system, this time its a discovery relating to the recently found tenth planet. The planet (unoficially called Xena) has a diameter about 30% greater then that of Pluto putting it at about 1,490 miles in diameter.

First of all, a hot arguement evolved out of UB313 ( Xena ) on whether it should be considered to be a planet or not.

For one thing, it is coming from Kupier Belt Objects which are not considered planets.

 

But other astronomers argue that pluto is also a KBO, then why is it called a planet then??
