What was discovered
The discovery of Eris, more massive than Pluto, forced the IAU to define 'planet' in 2006 and create the dwarf planet category, which includes Pluto, Ceres, Eris, Makemake and Haumea.
The discovery of Haumea was the subject of a priority dispute between Brown and Ortiz's group (Sierra Nevada, Spain).
What it led to
- IAU planet definition (2006)
