Abstract:

NEOROCKS is an EU HORIZON project which was started in 2020. This project is devoted to improve our knowledge of the Near Earth Objects (NEO) population using different observational techniques. In this work the result of photometric observations of small NEOs that were conducted within the NEOROCKS project by the team at Paris observatory in the past three years will be presented. Photometric observations were performed using French assets, in particular the 1.2m telescope at the Haute-Provence observatory. Several observational runs were performed in 2020-2023 and more runs are still scheduled in 2023. To date, we observed 159 NEOs. Among them, 85 objects are classified as Potentially Hazardous Asteroids (PHAs), representing NEOs with minimum orbital intersection distance MOID < 0.05 au and absolute magnitude H < 22. The majority observed NEOs fall into the H = 17-23 magnitude range and have diameters of less than 500 m. Results of taxonomic classification of these objects will be presented.
