SINEO: Spectroscopic Investigation of Near Earth Objects

In this paper we present the results obtained until now from our spectroscopic survey in the visible and Near Infrared Region (NIR) of Near Earth Objects (NEO), named SINEO, started in 2000. Up to now we have obtained a data set of about 150 spectra, most of them in the visible range (0.40-0.95 μm) and about half of them in the whole region 0.40-2.5 μm. The observations have been performed with the NTT of ESO (Chile) and the Telescopio Nazionale Galileo (TNG) at the Canary Islands. We present the taxonomic classification of the objects, their linkage with meteorites and the influence of space weathering.
