"Atarashii Taiyoukei" (The New Solar System) by WATANABE Jun-ichi

On the summer in 2006 Pluto was eliminated from the solar system. Why Pluto should be excluded? It seems that many Pluto-like heavenly bodies have been discovered with the improvement of the observation technique. The author worked hard for the decision as a member of Planet Definition Committee of IAU (International Astronomical Union). You can also enjoy this book by watching the beautiful pictures (^_^)
