Pluto & Eris

Answers.com says:

Spotlight: Easy come, easy go. On this date in 2005, astronomers announced the discovery of Eris, a heavenly body slightly larger than Pluto, and called it the 10th planet. The International Astronomical Union did a little further research and decided that both bodies were too small to be official planets; both Eris and Pluto were demoted to the official designation of dwarf planet. Along with its moon, Dysnomia, Eris is the most distant known object in orbit around the sun.
