re: vote comes August 24 on a new definition of "planet", which would, if passed at the meeting of the International Astronomers Union (IAU), create a tiered definition: "...Pluto would remain a planet but would fall into a newly created category called Plutons, which are distinguished from classical planets in that they take longer than 200 years to orbit the sun./Pluto would be joined in this category by two other celestial bodies, Xena and Charon, while another, Ceres, would be known as a dwarf planet./In all, 12 planets would be listed in our solar system, at least for the time being..."...
