t be much less affected by perturbing planets than is the angular momentum exchange (which relates to e). hence， the eccenicities of venus and earth can be disturbed easily by jupiter and satu， which results in a positive correlation in the angular momentum exchange. on the other hand， the semimajor axes of venus and earth are less likely to be disturbed by the jovian planets. thus the energy exchange may be limited only within the venus–earth pair， which results in a negative correlation in the exchange of orbital energy in the pair.
as for the outer jovian planetary subsystem， jupiter–satu and uranus–neptune seem to make dynamical pairs. howev
