Most of us, including myself grew up learning about the 9 planets in our Solar System. But that model was shattered when the Internation Astronomical Union voted in August 2006 to demote Pluto as a planet, relegated to the realm of just another Kuiper Belt Object. Mike Brown, the astronomer who’s research directly lead to the declassification of Pluto as planet just wrote a book, How I Killed Pluto and Why It Had It Coming.
The book is available at www.amazon.com
