In 2005 Mike Brown discovered Eris which was slightly larger than Pluto. This discovery sparked a series of international debates resulting in the demotion of Pluto to a dwarf planet. Brown recounts his controversial discovery in this part memoir and part planetary saga in How I Killed Pluto and Why It Had It Coming.
