mp|(119070) 2001 KP|77 (also written (119070) 2001 KP77) is a 4:7 resonant Trans-Neptunian object (TNO) located in the Kuiper belt. It was discovered on May 23, 2001, by Marc W. Buie at Cerro Tololo.

Color

mp|2001 KP|77 has the highest, and thus reddest measured B-V color index of any TNO. On April 19, 2002, mp|2001 KP|77 set a TNO record B-V of 1.544. In the visible spectrum mp|2001 KP|77 would appear an orange-brown depending on its albedo.

ize

Based on an absolute magnitude (H) of 6.93, mp|2001 KP|77 is estimated to be between 110 - 240km in diameter. [ [http://cfa-www.harvard.edu/iau/lists/Sizes.html Conversion of Absolute Magnitude to Diameter] ]
