Thanks Raoul

I am pleased with the IAU's decision. It is probably the best result possible/is an excellent compromise.

A like the new class of planet - a Pluton (in honor of Pluto)

"Plutons are distinguished from classical planets in that they reside in orbits around the Sun that take longer than 200 years to complete (i.e. they orbit beyond Neptune). Plutons typically have orbits that are highly tilted with respect to the classical planets (technically referred to as a large orbital inclination). Plutons also typically have orbits that are far from being perfectly circular (technically referred to as having a large orbital eccentricity). All of these distinguishing characteristics for plutons are scientifically interesting in that they suggest a different origin from the classical planets."

What a marvelous day to be alive. The day when our solar system was finally defined.
