The asteroid 2001 SN263 was revealed in February 2008 as the first known near-Earth triple asteroidal system (Nolan et.al, 2008). Using preliminary information about the orbit and the physical composition of such asteroid (Becker et. al, 2009), we have performed numerical integrations in order to study the orbital dynamics of the system, and the effects of the gravitational perturbations of the planets Mars, Earth and Jupiter on such system. We discuss the evolution of each body when only the three asteroids are considered (mutual perturbation), and the effects due to Jupiter and Mars, and also due close-approaches between the triple asteroid and the Earth. Then, we analyze a system composed by seven bodies: Sun, triple asteroidal system, Mars, Earth and Jupiter, in order to identify equilibrium regions and propose several orbits for a spacecraft in a potential space mission to explore this system.
