August 24, 2006 - Prague: Ending years of debate, astronomers today decided to revoke Pluto's platentary status, instead relabeling it as a "Dwarf Planet."
The vote, taken among 424 astronomers (less than 5% or the world's total), took place at the annual meeting of
the International Astronomical Union (IAU) in the Czech Republic. "I'm embarassed for astronomy," said Alan Stern of NASA's
New Horizon's mission to Pluto and a scientist at the Southwest Research Institute, "This vote stinks." Nevertheless,
the decision will stand for now, the effects of which will be most noticable on the school textbook industry who will
have to update their books accordingly. The vote established three categories for objects in our solar system -- Planets,
Dwarf Plantes and Small Solar System Bodies. Pluto was reclassified as a Dwarf Planet. Read more
