(119070) 2001 KP77

(119070) 2001 KP₇₇ (better known as 2001 KP77) is a 4:7 resonant Trans-Neptunian object (TNO) located in the kuiper belt. It was discovered on May 23, 2001, by Buie, M. W. at Cerro Tololo.

2001 KP₇₇ has the highest, and thus reddest measured B-V color index of any TNO. On April 19th, 2002, 2001 KP₇₇ set a TNO record B-V of 1.544. In the visual spectrum 2001 KP₇₇ would appear an orange-brown because of its low albedo.

Based on an absolute magnitude (H) of 6.93, 2001 KP₇₇ is estimated to be between 110 - 240km in diameter.
