A planetary system with at least seven planets has been found around the star HD 10180. However, the traditional Keplerian and n-body ﬁts to the data provide an orbital solution that becomes unstable very quickly, which may quest the reliability of the observations. Here we show that stable orbital conﬁgurations can be obtained if general relativity and long-term dissipation raised by tides on the innermost planet are taken into account.
