The trans-Neptunian objects

After reading this book, we understand why Pluto was demoted planets of the Solar System. The components of the Kuiper belt are well defined with all trans-Neptunian objects. The chapters are well argued with photos, graphics and easily understood simulations. Inserts more or less give us explanations provided more detail on certain points raised.
The whole house of easy understanding for anyone interested in astronomy with acquired just pushed. I do not recommend this book to a child who will leave soon overtake.
