The potentially hazardous Asteroid (214869) 2007 PA8: An unweathered L chondrite analog surface
Résumé
In this paper we present the results on the polarimetric and spectroscopic observations of the potentially hazardous Asteroid (214869) 2007 PA8 obtained during its favorable apparition in October-November 2012, when it approached the Earth at the minimal distance of 0.043 AU. Polarimetry was carried out at the NOT in the B, V, R, and I bands covering both low (12-23°) and large phase angles (88-99°). Spectroscopy in the visible and near infrared range was obtained at the TNG telescope.
