Discovery of ErisEdit

Eris was discovered by Mike Brown, Chad Trujillo and David Rabinowitz. Eris was spotted by them on January 5, 2005, with images taken October 21, 2003. This discovery was announced on July 29, 2005, the same day as Makemake was announced, and 2 days after Haumea was announced. The team had been looking for large TNO's frantically for a while, and after reviewing images taken a year and a half earlier, Eris was seen moving against the stars.
