Palomar Find Makes Discovery News Top 10 of the Decade

Discovery News has put out their list of the Top 10 Discoveries of the Decade and their list of Top 10 Space Discoveries of the Decade.

On both lists is the 2005 discovery of the world known as Eris. Knowledge of the existence of Eris, named after the Greek goddess of discord, helped to push Pluto out of the planetary roll call. In 2006, the International Astronomical Union officially proclaimed both Pluto and Eris to be part of a new, non-planet, classification known as "dwarf planets."

The discovery was made using the Palomar Observatory's 48-inch Samuel Oschin Telescope by the team of Mike Brown (Caltech), Chad Trujillo (Gemini Observatory) and David Rabinowitz (Yale).

The discovery was made as a part of survey of the outer solar system using the Palomar QUEST camera and the Samuel Oschin Telescope at the Palomar Observatory.
