The Pluto Files by Neil deGrasse Tyson

The Rise and Fall of America's Favorite Planet

A lively, accessible account that traces Pluto’s discovery and the scientific, political, and cultural battles leading to its 2006 reclassification as a dwarf planet; blending history, personal anecdotes from the narrator’s role at a major planetarium, and clear explanations of the science and institutional decisions, the book explores how astronomical definitions are made and how the public responds when long-held ideas about the solar system change.
