Asteroids and comets - being relics of the early Solar System stages - are fundamental to our understanding of its formation and history; and possibly for the origin of life as a source of water and organic material delivery onto our primitive Earth. One still intriguing source of long period comets with large eccentricities and inclinations, is the hypothetical Oort cloud. Such objects can be triggered to move in the inner Solar System region as well as being ejected to interstellar space; similarly inter-stellar objects originating from other stars have also visited our Solar System. This outer region being the interface of the Solar System dynamics with the stellar environment and the galactic potential, it tackles different domains of astronomy. All having moreover shown recent development thanks to the results of recent European Gaia mission data release and show potential with the future Gaia releases, LSST and other survey programmes, and the Comet Interceptor mission.
