Eris
Eris is a massive dwarf planet. It was discovered in 2005 and it is more massive than Pluto by 27 percent.
Yes, Eris is the largest known Dwarf Planet (but there could be larger ones that have not been discovered yet).
The dwarf planet, Eris, was discovered on January 5, 2005. It was discovered by a team at the Palomar Observatory in San Diego County, California.
Eris seems likely to fall into the same classification as Pluto; a 'dwarf planet". It seems likely that there are more large planets yet to be discovered, because of the unexplained gravitational disturbances in the orbit of Neptune. But Eris is not it.
The dwarf planet discovered in 2004 is Haumea. It was officially recognized as a dwarf planet by the International Astronomical Union in September 2008.
They were calling it 2003UB313, now they are calling it Eris.
If a dwarf planet were discovered farther from the Sun than Eris, its orbital speed would be slower than that of Eris. According to Kepler's laws of planetary motion, the farther an object is from the Sun, the slower its orbital speed due to the weaker gravitational pull. Thus, this newly discovered dwarf planet would have a longer orbital period and a reduced speed compared to Eris.

Ceres was discovered in 1801. Eris was discovered in 2005.
