figures， they show negative correlations in exchange of energy and positive correlations in exchange of angular momentum. the negative correlation in exchange of orbital energy means that the two planets form a closed dynamical system in terms of the orbital energy. the positive correlation in exchange of angular momentum means that the two planets are simultaneously under certain long-term perturbations. candidates for perturbers are jupiter and satu. also in fig. 11， we can see that mars shows a positive correlation in the angular momentum variation to the venus–earth system. mercury exhibits certain negative correlations in the angular momentum ver
