A THEMIS VIS Investigation into the Potential for Small Meteoroid Impacts Associated with the Orbital Pass of Near-Mars Asteroid 2007 WD5

The idea of hypothetical, unseen debris fields associated with asteroidal parent bodies, either as cob-ble/boulder-sized families, or as particulate meteoroid streams, has been entertained for decades. Such objects could result from low-energy impact ejecta, whole-body fragmentation from im-pacts, or tidal disruption of weak bodies from planetary interac-tions. Dispersion is likely to occur over timescales that depend in large part on the energy of disruption [1]. However, because the smaller of these objects would be beneath the detection limits of ground-based optical systems, very little is known about their true occurrence, size-frequency distribution, or persistence as populations. With the recent close Mars-pass of Near-Mars Asteroid (NMA) 2007 WD
