The Pluto Files
Encyclopedia
The Pluto Files: The Rise and Fall of America's Favorite Planet is a book written by astrophysicist and Hayden Planetarium
director Neil deGrasse Tyson
. The book is about Pluto
, which was demoted to the status of dwarf planet
in August 2006 by the International Astronomical Union
, thereby relinquishing it of its planet-hood. The book also focuses on the fact that many Americans rallied their support for this icy dwarf on the edge of the Solar System
because it was discovered by an American.
The book was given a good review by Jon Stewart
in a guest segment with Dr. Tyson on the Daily Show. During the interview, Stewart humorously lauded the book as "the most exciting book about Pluto you will ever read in your life," as well as "the compelling story of how [Tyson] destroyed Pluto's life."
The book explains in full detail the journey of Pluto's life from its days as Planet X
, to its discovery in the early 20th century and all the way to its final title as a Trans-Neptunian object
