Publisher Description

The solar system most of us grew up with included nine planets, with Mercury closest to the sun and Pluto at the outer edge. Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of adding one more planet to our solar system, Brown’s find ignited a firestorm of controversy that culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about.

A heartfelt and personal journey filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever imagined exploring the universe—and who among us hasn’t?

It's an astronomical love story

Want to know the human story behind the exploration of the universe? This is the next book you need to read. Beautifully written, with one of the most exciting astronomical discoveries of our time (i.e. The detection of dwarf planet Eris) and subsequent controversy surrounding the demotion of Pluto wonderfully described. Mike Brown has done a top notch job with this one.

Great little book!

I loved this book, I amp fascinated by astronomy and this book does a great job of weaving science and narrative. I couldn't put it down.

This book is a masterpiece, it will guide you through different astronomic terms, yet it won't be boring. I am personally not an astronomer and have given not much attention to astronomy, but this book was so self explanatory that it was even fun to read.
Great book, read it.
