How I Killed Pluto and Why It Had It Coming

Most of us grew up believing there were nine planets in the Solar System — from Mercury near the Sun to Pluto on the distant outer edge. But in 2005, astronomer Mike Brown discovered what seemed to be the tenth planet — Eris, an object about the same size as Pluto.
Instead of resting on his laurels, Brown ignited a fiery debate that turned the quiet world of astronomy into a buzzing hornet’s nest. By then, astronomers had already identified other objects beyond Neptune that rivaled Pluto in size. So the question arose: should all of them be considered planets?
In the end, the debate led to Pluto’s demotion — and Brown found himself receiving angry letters from fellow scientists, amateur astronomers, and even schoolchildren — all because of the very discovery he had dreamed of for years.

Filled with drama and humor, How I Killed Pluto and Why It Had It Coming is a candid, first-person account of one of the most turbulent chapters in modern astronomy.
It’s a story of scientific passion, controversy, and cosmic perspective — and it invites readers to rethink our place in the universe.

Perfect for anyone who dreams of exploring the cosmos.
