"2007 OR10 is the largest unnamed world in our solar system and the third largest of the current roster of about half a dozen dwarf planets. The recent study also found that the object is quite dark and rotating more slowly than almost any other body orbiting our sun, taking close to 45 hours to complete its daily spin. The revised measurement of the planet's diameter, 955 miles (1,535 kilometers), is about 60 miles (100 kilometers) greater than the next largest dwarf planet, Makemake, or about one-third smaller than Pluto."

Astronomers Meg Schwamb, Mike Brown and David Rabinowitz discovered 2007 OR10 on July 17, 2007. Mike Brown expects to give it a name in 2017.
