Hate Mail from Third Graders

"It's not easy being a public enemy," writes Neil deGrasse Tyson in his book The Pluto Files . When Neil's museum grouped Pluto not among the planets but rather with icy comets in an obscure region called the Kuiper Belt, he heard from thousands of outraged Pluto defenders. It's tough being called a heartless Pluto-hater, particularly by a dismayed eight-year-old. In this slide show, peruse a few of the letters elementary schoolkids sent Neil, and see how their tone shifted over the years, as the public slowly came to accept Pluto's fall from planethood.—Susan K.
