The Pluto files

In August 2006, the International Astronomical Union voted Pluto out of planethood. It is a wonder Pluto has any fans, yet during the mounting debate over Pluto's status, people rallied behind the extraterrestrial underdog. Pluto is entrenched in the American cultural, patriotic view of the cosmos and Neil deGrasse Tyson is on a quest to discover why. Only Tyson can tell this story: he was involved in the first exhibition to demote Pluto and consequently, Pluto lovers have freely shared their opinions with him. In his typically witty way, Tyson explores the history of planet classification and America's obsession with the "planet" that has recently been judged a dwarf.
