(101429) 1998 VF31 is a small asteroid which orbits the L5 point trailing 60° behind the orbit of Mars. It is in a highly stable orbit around the Martian Lagrange point, and was originally thought to be spectroscopically similar to 5261 Eureka, suggesting they may both be primordial Martian asteroids.
Spectroscopic observations through 2007 indicate that it has a large proportion of metal and achondrites on its surface (either with or without a mesosiderite contribution); which could also indicate that the surface regolith has undergone space weathering. These observations also reveal differences in the spectra with 5261 Eureka, suggesting they may not be related to each other after all.
