It’s hard to imagine, but in 1992 astronomer Mike Brown didn’t know what the Kuiper Belt was. He had never heard of it. But just a few years later in 1999, he bet another scientist that within five more years he would find another planet out there at the edge of the solar system, past Pluto. It took a five-day extension of the bet, but Brown did it. And so began the death of Pluto as a planet, but the rise of a whole new class of objects called dwarf planets. Brown has written a book about his adventures as a planet hunter and eventual planet killer, called “How I Killed Pluto and Why it Had it Coming.”
