We present the results obtained so far from our long-term spectroscopic survey of Near-Earth Objects (named SINEO), started few years ago and performed with the telescopes NTT of ESO at La Silla and TNG at La Palma (Canarias). The data are a set of more than 100 visible and near infrared spectra almost completely reduced, analyzed and partly published. It represents one of the largest set of spectroscopic data on NEOs and particularly interesting for its spectral extention (0.45-2.5 micron). We will discuss their taxonomy and the overall compositional linkage with the principal sources of near-Earth objects, namely the Main Belt and the outer Solar System. We will discuss then their link with meteorites and the influence of space weathering on their spectral properties.

Abstract
We present the results obtained so far from our long-term spectroscopic survey of Near-Earth Objects (named SINEO), started few years ago and performed with the telescopes NTT of ESO at La Silla and TNG at La Palma (Canarias). The data are a set of more than 100 visible and near infrared spectra almost completely reduced, analyzed and partly published. It represents one of the largest set of spectroscopic data on NEOs and particularly interesting for its spectral extention (0.45-2.5 micron). We will discuss their taxonomy and the overall compositional linkage with the principal sources of near-Earth objects, namely the Main Belt and the outer Solar System. We will discuss then their link with meteorites and the influence of space weathering on their spectral properties.Pubblicazioni consigliate
