Meet the Plutons

Astronomers meeting in Prague have drafted a proposal that would make way for a new planetary classification - the pluton(1). In addition to the eight "classic" planets, there would be three plutons-- Pluto, Charon, and "Xena," and more could be added as they are discovered. The pictured graphic(2) by Calvin J. Hamilton shows the size of Pluto and Charon compared to the United States.
