136472 Makemake is apparently the largest dwarf planet in the Sol system.
It was discovered by a team led by Michael E. Brown at the Palomar Observatory on March 31, 2005, and is named after the creator god in Rapa Nui mythology.
Makemake has one moon, informally called "Makemake 2" or "MK2" until the IAU can get around to giving it a name. It is unusual in that its reflectivity is substantially lower than its primary's.
