The man who ‘killed’ Pluto

In 2005 Professor Mike Brown and his team discovered a new dwarf planet at the edge of our solar system.

He spotted Eris in the Kuiper belt – a region of icy objects beyond Neptune.

It was more massive than Pluto and left astronomers with a dilemma: whether to add it and other larger bodies, to the list of planets or to strip Pluto of its 75-year status as the ninth planet.

Mike Brown spoke to Witness History about his discovery and the public outcry that followed.
