rrhhhuummble rhuubbaarb rrhhhummble. Crazy bureaucrats. Yes Pluto stays a planet, and 2003 UB313 becomes a planet, along with Sedna, Ceres and

Basically anything that has enough mass to gravitationally form a spherical object (I don't think there is a statement about how spherical
) can be called a planet. I'm now counting down the days til our solar system tops the 100 planets mark.
