Small Solar System bodies, including asteroids, comets, satellites, and interplanetary dust particles (IDPs), preserve clues for the understanding of the origin and evolution of the Solar System and the investigation of the sources of the building blocks of life. Many discoveries have been made in recent years through ground-based and space-borne observations and in situ explorations using spacecraft. Evident and precise data on the origin and evolution of the Solar System have been obtained by analyses of extraterrestrial materials such as meteorites, IDPs, and the samples returned by space missions. New insights are expected by the collaboration of these data-based results with theoretical and experimental studies. In this session. new results of theoretical, experimental, and observational studies on small Solar System bodies are focused, as well as the latest results of remote sensing and sample analysis by OSIRS-REx and DART missions. Scientific expectations are also discussed for the high-sensitive large-area observatories such as LSST and JWST and for future planetary missions like Hayabusa2#, MMX, Destiny+, Hera, Comet Interceptor, Lucy, and Psyche. Topics on the science and instruments of the Japanese next small body mission, whose working group studies have just started, as well as the studies for the planetary defense, are also within the scope of this session.
