(119070) 2001 KP77 (also written (119070) 2001 KP77) is a 4:7 resonant[1] trans-Neptunian object (TNO) located in the Kuiper belt. It was discovered on May 23, 2001, by Marc W. Buie at Cerro Tololo.

Color[edit]

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

Size[edit]

Based on an absolute magnitude (H) of 6.93, 2001 KP77 is estimated to be between 110 – 240 km in diameter.[3]
