Plutons, its not a particle, its the name of a new class of planets
MSNBC: The controversy over whether Pluto is really a planet reached a new milestone today, as a committee of the International Astronomical Union released a copy of report recommending a new class of planets for the solar system. Unlike predictions made last week astronomers will not call this new classification dwarf planets, but plutons instead, to highlight Pluto's special position in this new classification. Under the new classification, which can basically be described as round objects that orbit the sun, more than 40 other objects in the solar system could be classed as Plutons. Astronomers will vote on the proposal on the 25 August. It is unknown whether the IAU has enough votes to pass the measure.
