In the recent past, space agencies moved towards the exploration of our local neighborhood, studying the asteroids. They are indeed very useful to understand the history and formation of our solar system. But, unfortunately, today few missions have been planned: the most important were the Hayabusa 1 and 2 by JAXA, and OSIRIS-REx by NASA. The growth of Near Earth Asteroids (NEA) discoveries, have increased the awareness and the probability of futures Earth impacts, causing the end of life on our planet. In recent years, numerous asteroids have been classified as potential hazards, and more informations are needed on their physical properties and their orbital parameters to better predict their future orbits.
