Review: “How I Killed Pluto and Why it Had it Coming” — Plus win a copy!


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.”

(Read our exclusive Q & A with Mike Brown!)

His book is a highly readable, first person account of an astronomer who, by chance, realized he had remarkable penchant for discovering small, far away objects. The book is filled with humor, candor, geeky tendencies (he thought the first sonogram of his daughter looked like images from Venera 2 spacecraft from Venus), engaging personal anecdotes – and even romance, intrigue, mystery, fatherly love, and science.

“Discovery is exciting,” Brown writes in his book, “no matter how big or small or close or distant. But in the end, even better is discovering something that is capable of transforming our entire view of the sun and the solar system.”

And Brown’s discoveries have transformed our view of the solar system (some people have changed the world — how many can claim they have changed the solar system?!)

The discoveries of more objects in the Kuiper Belt turned on the heat of the debate of whether everyone’s favorite misfit planet, Pluto, was actually a planet or just a member of a new, quickly growing class of what are now called dwarf planets.

From this, some will claim, our planetary mnemonic went from “My Very Educated Mother Just Served Us Nine Pizzas” to “Mean Very Evil Men Just Shortened Up Nature.”

Mean and evil or educated? You decide.

  1. Couldn’t someone skew their chances by sending many emails from different accounts?

    Perhaps this would be better as a competition, like “Suggest a new mnemonic for the 8 planets” and pick 5 of the best.

  2. Hogwash…
    Say what you want, even write a book. There are still 9 planets and Pluto is one of them. Poor Pluto is like a cute, little, hungry puppy left out in the cold to fend for itself. To all the cruel people who have disregarded Pluto…
