The potentially hazardous Asteroid (214869) 2007 PA8: An unweathered L chondrite analog surface

Our spectral and polarimetric analysis indicate that 2007 PA8 has a young and fresh surface almost unweathered, similar to L-type chondrites. These results, together with dynamical simulations made by Nedelcu et al. (Nedelcu, D. A., Birlan, M., Popescu, M., Badescu, O., Pricopi, D. [2014]. Astron. Astrophys. 567, L7, 5pp.) and Nesvorny et al. (Nesvorny, D., Vokrouhlicky, D., Morbidelli, A., Bottke, W. F. [2009]. Icarus 200, 698-701), indicate that 2007 PA8 may be a member of the Gefion family recently ejected from the 5:2 resonance and a potential source of L chondrites.
