How I Killed Pluto and Why It Had It Coming

Most of us grew up believing that there were nine planets in the solar system, with Mercury near the sun and Pluto at the far outer edge. Then, in 2005, Michael Brown discovered a supposed tenth planet, Eris, about the size of Pluto. But instead of resting on his laurels, Brown sparked a heated debate that turned the otherwise quiet world of astronomy into a hive of activity. By then, other objects beyond Neptune were known to be no less massive than Pluto. So should they be considered planets? The debate ultimately resulted in Pluto being removed from the planetary pantheon, and Brown was bombarded with angry letters from fellow scientists, amateur astronomers, and even schoolchildren—all for the discovery he had dreamed of for years.

Filled with drama and humor, How I Killed Pluto and Why It Had to Be is the confession of a scientist who, despite widespread condemnation, had to demote everyone's favorite planet. It is a first-person account of the most turbulent year in the history of modern astronomy, inspiring deeper reflection on our place in the cosmos.
