(310071) 2010 KR59, provisional designation 2010 KR59, is a trans-Neptunian object, approximately 110 kilomters in diamter. The object is trapped in a 1:1 mean motion resonance with Neptune, and rotates nearly every 9 hours around its axis.

Discovery
(310071) 2010 KR59 was discovered on May 18, 2010 at 7:45 UT by the WISE spacecraft. The WISE telescope scanned the entire sky in infrared light from January 2010 to February 2011.
Orbit
(310071) 2010 KR59 follows a very eccentric orbit (eccentricity of 0.57) with a semi-major axis of 29.97 AU and an inclination of 19.76º. Its aphelion goes into the trans-neptunian belt but its perihelion is relatively close to Saturn's orbit.
Physical properties
(310071) 2010 KR59 is a rather large minor body with an absolute magnitude of7.7 that translates into a diameter close to 100 kilometers. The discovering WISE/NEOWISE mission estimates a diameter of 7002110060000000000♠110.060 kilometers with a large error margin of 30.820 km.
Co-orbital with Neptune
(310071) 2010 KR59 follows a complicated and short-lived horseshoe orbit around Neptune. Classical horseshoe orbits include the Lagrangian points L3, L4 and L5, this object horseshoe path goes from the L4 point towards Neptune reaching the L5 point and back. It will become a quasi-satellite of Neptune in about 5,000 years.
