NOVA shares some of the "hate mail" sent by children to Neil deGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History in New York City, after Pluto was demoted from a planet to a comet. What's interesting about this collection of letters is "how their tone shifted over the years, as the public slowly came to accept Pluto's fall from planethood." EXCLAMATION!
