Sayonara Pluto

It's offical. Pluto is now an ex-planet. Well more correctly a "dwarf planet", but clearly a second-class citizen in our solar system's celestial body rankings.

At 2,274km in diameter, Pluto is smaller than seven of our solar system's moons, but now that we finally have a definition of "planet", it fails the test because its oblong orbit overlaps with Neptune's.

And thus earth's scientists fired the first salvo in our future interstellar war with the aliens of Pluto, which I am sure will begin in 2015 when the spacecraft "New Horizons" becomes the first ship to reach this far away... thing.
