Statistical orbital evolution of comet 41P and its 200 clones over 10⁵ yr: 5 × 10⁴ backward in time and 5 × 10⁴ forward. The top panel corresponds to a pure gravitational model, while in the bottom panel non-gravitational forces are included. In both panels different colours refer to different regions in the solar system, namely: red for those in the Jupiter family region, clear blue are Centaurs, yellow are Halley types, and dark blue are trans-Neptunians. Labels A, B, C, and D mean the time spent in the Jupiter family region at different confidence levels, i.e., % of clones in that region. Therefore, A is 100%, B is 90%, C is 80%, and D is 70%.
