Is Pluto a Planet?

The book explores the pivotal decision made by the International Astronomical Union in 2006 to redefine the criteria for what constitutes a planet, resulting in Pluto's reclassification as a "dwarf planet." It delves into the implications of this decision, the controversy surrounding it, and the broader impact on our understanding of the solar system. Through this lens, the author examines the dynamics within the astronomical community and the significance of Pluto's new status.
