Abstract: Numerous small bodies, such as comets, asteroids, etc. bear key information of the history of our Solar System as well as the emergence and migration of life in it. Past decades have seen a rapid development in our knowledge of these bodies, and some of the most exciting discoveries are associated with the active nature of various types of small bodies. I will first talk about activities of comets, focusing on latest findings from rendezvous missions like Rosetta. I will then introduce other active small worlds across the Solar System and what insight their activities might bring to our understanding of Solar System’s evolution.
