The Pluto Files
Since its discovery in 1930, Pluto has held a warm place in the public imagination. So when the American Museum of Natural History's Hayden Planetarium stopped calling Pluto a planet, director Neil deGrasse Tyson found himself at the center of a firestorm. But what is it about this cold, distant, icy rock that captures so many hearts? Is it a planet? Is it just an ice ball? The debate continues, as NOVA travels cross-country with Tyson to find out.
