(225088) 2007 OR10 is a trans-Neptunian object (TNO) approximately 1500 kilometers in diameter. It is the third-largest known body in the Solar System beyond Neptune, and the largest known body in the Solar System without a name. According to current estimates as of May 2016, it is slightly larger than Makemake or Haumea, and is hence almost certainly a dwarf planet. It has one known moon.
