More proof Pluto isn’t a planet

SPACE.com — Dwarf Planet Outweighs Pluto

The dwarf planet that effectively forced astronomers to strip Pluto of its planethood is not only bigger than the former ninth planet, but also much more massive, a new study finds.

Michael Brown, a planetary scientist at Caltech, and his graduate student Emily Schaller have determined that Eris, discovered in 2005 by Brown and his team, is about 27 percent more massive than Pluto.
