2010 XG11

2010 XG₁₁ is an Amor near-Earth asteroid. 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. Three precovery images are known from 1 July 1995. With an observation arc of 16 years, the orbit is well determined with an orbital uncertainty of 0. With an absolute magnitude of 20.0, the asteroid is about 270–590 meters in diameter.

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. On 29 July 2014 the asteroid passed 0.00805 AU (1,204,000 km; 748,000 mi) from Mars.
