[P-PS07] Solar System Small Bodies: Explorations of Ryugu, Bennu, and the Solar System at Large

convener:Taishi Nakamoto(Tokyo Institute of Technology), Tatsuaki Okada(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Dante S Lauretta(University of Arizona), Masateru Ishiguro(Department of Physics and Astronomy, Seoul National University)

Small Solar System bodies, including asteroids, comets, satellites, and inter-planetary dust particles, are interesting and provide lots of information on the origin and evolution of our Solar System. They can be remotely sensed by telescopes, be visited by spacecraft and studied at high resolution in a variety of wavelengths from IR to visible, UV, X-rays, and gamma rays, and even with neutrons. In addition, recently spacecrafts have been sent to return samples. In this session, all the contributions on the small solar system bodies are welcome. But this year, we especially welcome contributions on recent advances on the study of Ryugu and Bennu whether obtained by rendezvous spacecraft, remote sensing, or other methods.
