Pluto demoted, Aliens must be laughing

As of yesterday, Pluto is officially no longer a planet and we now live in an 8-planet solar system. However the new definition is ridiculous (Earth hasn't "cleared the neighbourhood around its orbit" and neither has Neptune because it crosses Pluto's orbital path):

"A planet within our solar system is defined by the International Astronomical Union as a celestial body that is in orbit around the Sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and has cleared the neighbourhood around its orbit. Those bodies which fulfill the first two conditions but not the third are dwarf planets if they are not satellites." ----wikipedia Planet entry as redefined yesterday by the International Astronomical Union

So called "dwarf planets" are not even planets according to the definition and less than 5% of the world's astronomer community voted for the change, which is simply wrong. There is currently a move to have the new definition overturned or at least updated. Today I am not proudly Human.

• Wikipedia is of course up to date - keep up to date by reading the 2006 redefinition of planet topic, and see Pluto, Planet, Solar System, Dwarf Planet.
