Eris, the largest dwarf planet. Eris is a dwarf planet that lies at the outer reaches of our solar system. It was discovered in 2005 by professional astronomers who were examining images taken at California's Palomar Observatory two years previously.
When Eris was first discovered in 2005, it was thought to be significantly larger than Pluto. Originally, it was submitted as the tenth planet in the solar system. Ultimately, however, Eris' discovery was a big reason astronomers demoted Pluto to dwarf planet status in 2006.ris' surface was also found to be extremely reflective, bouncing back 96 percent of the light that strikes it. That makes Eris one of the most reflective bodies in the solar system, roughly on par with Saturn's icy moon Enceladus. [ Top 10 Extreme Planet Facts ].
