Mars Trojans in 
JPL Orbit Viewer.

The four currently listed Mars Trojans -- asteroidal objects that share the orbit of Mars. They travel inclined to the plane of that orbit and stay ahead of or behind Mars at the Lagrange L4 or L5 positions. The three blue dots at L5 are, from the bottom up, newly discovered 2007 NS2, 5261 Eureka (1990 MB), and 101429 1998 VF31, while 121514 1999 UJ7 resides at L4. Mars is the red dot and the other terrestrial planets are green dots. The planetary positions are today's, and note that the Mars L5 point is currently at opposition (in line with Earth from the Sun). This diagram was composited at A/CC from the JPL Orbit Viewer. See below for news about 2007 NS2.
