NEOROCKS Characterization Program of Near-Earth Asteroids Previously Observed with Radar

The NEO Rapid Observation, Characterization and Key Simulations (NEOROCKS) project is funded (2020-2023) through the H2020 European Commission program to improve our knowledge on near-Earth objects by connecting expertise in performing small body astronomical observations and the related modeling needed to derive their dynamical and physical properties. The Instituto de Astrofísica de Canarias (IAC), and in particular members of the Solar System Group, participate in the NEOROCKS project and currently lead one specific task: to collect observational data, mainly in the visible wavelengths, of NEAs that have been observed in the past using the Arecibo Planetary Radar. In this work we present preliminary results, focusing on those targets having high signal-to-noise ration radar data.
