The aim of our study is to investigate the dynamics of possible comets in theHD 10180 system. This investigation is motivated by the discovery of exocometsin various systems, especially $\beta$ Pictoris, as well as in at least tenother systems. Detailed theoretical studies about the formation and evolutionof star--planet systems indicate that exocomets should be quite common. Furtherobservational results are expected in the foreseeable future, in part due tothe availability of the Large Synoptic Survey Telescope. Nonetheless, the SolarSystem represents the best studied example for comets, thus serving as a primemotivation for investigating comets in HD 10180 as well. HD 10180 is strikinglysimilar to the Sun. This system contains six confirmed planets and (at least)two additional planets subject to final verification. In our studies, weconsider comets of different inclinations and eccentricities and find an arrayof different outcomes such as encounters with planets, captures, and escapes.Comets with relatively large eccentricities are able to enter the inner regionof the system facing early planetary encounters. Stable comets experiencelong-term evolution of orbital elements, as expected. We also tried todistinguish cometary families akin to our Solar System but no clear distinctionbetween possible families was found. Generally, theoretical and observationalstudies of exoplanets have a large range of ramifications, involving theorigin, structure and evolution of systems as well as the proliferation ofwater and prebiotic compounds to terrestrial planets, which will increase theirchances of being habitable.
