Long-term evolution of the HD 10180 planetary system over 150 Myr starting with the orbital solution from Table 7. The panel shows a face-on view of the system. x and y are spatial coordinates in a frame centered on the star. Present orbital solutions are traced with solid lines and each dot corresponds to the position of the planet every 10 kyr. The semi-major axes (in AU) are almost constant, but the eccentricities undergo significant variations (Table 8).
