(121514) 1999 UJ7
(121514) 1999 UJ7 is a small asteroid orbiting near the L4 point of Mars (60 degrees ahead Mars on its orbit). As of September 2011, (121514) 1999 UJ7 is the only known asteroid to orbit the leading L4 point of Mars, although at least three other asteroids orbit Mars's trailing L5 point: 5261 Eureka, (101429) 1998 VF31, and 2007 NS2. Not only does (121514) 1999 UJ7 orbit on the other side of Mars from other similar asteroids, its spectrum is different as well, which is puzzling because all of the Martian trojans seem to be in very stable orbits.
