Meteoroid impacts are an important source of neutral atoms in the exosphere of Mercury. Impacting particles of size smaller than 1 cm have been proposed to be the major contribution to exospheric gases ([2]). We have computed by means of N-body numerical integrations the orbital evolution of a large number of dust particles, in the size range between 5 - 100 μm, originating from both asteroidal and cometary sources. They migrate inward under the effect of drag forces until they encounter a terrestrial planet or eventually fall into the Sun. We have computed the flux of particles hitting Mercury's surface, the corresponding distribution of impact velocities and the asymmetries in the particles distribution on the Mercury orbit.
