Abstract

We aim to provide a taxonomic and compositional characterization of Multiple Asteroid Systems (MASs) located in the main belt (MB) using visible (0.45–0.85 μm) and near-infrared (0.7–2.5 μm) spectral data of 42 MB MASs. The compositional and mineralogical analysis is applied to determine meteorite analogs for the MASs, which, in turn, are applied to the MAS density measurements of Marchis et al.(Marchis et al.[2012]. Icarus 221, 1130–1161) to estimate the porosity of the systems. The macroporosities are ...
