    (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

    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

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