2010 XG11 is an Amor near-Earth asteroid.[2] It was discovered on 5 December 2010 by the Catalina Sky Survey at an apparent magnitude of 19.7 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope.[1] Three precovery images are known from 1 July 1995.[4] With an observation arc of 16 years, the orbit is well determined with an orbital uncertainty of 0.[2] With an absolute magnitude of 20.0,[2] the asteroid is about 270–590 meters in diameter.[3]

With a Mars-minimum orbit intersection distance of 0.002 AU (300,000 km; 190,000 mi), the asteroid currently makes closer approaches to Mars than it does Earth.[4] On 29 July 2014 the asteroid passed 0.00805 AU (1,204,000 km; 748,000 mi) from Mars.[5][6]
