dc.description.abstractThe so-called Martian Trojans are asteroids orbiting in the stability regions corresponding to the L4 and L5 Lagrangian points of Mars. Their existence is thought to date back to the early epochs of the solar system history. Out of the ten confirmed Martian Trojans, nine belong to L5 and only one belongs to L4. The asteroid (101429) 1998 VF31 (VF31 hereafter) is the only one non-Eureka family Martian Trojan asteroid in L5. Our study shows that VF31 surface is probably dominated by orthopyroxene. A previous study of the same asteroid explains the red slope by adding iron. The similarity that we found with lunar spectra and especially that the best matches are craters from highlands, where orthopyroxene is dominantly iron-rich, can explain the red slope and the positions and intensity of the spectral features. In spite of all uncertainties, we can rule out the possibility that this object belongs to any class of primitive low albedo objects and its most likely origin is the inner solar system.
