Abstract Orbital calculations of 25 planetesimals revolving in an annular zone around the Sun are performed in order to see their kinetic behavior, especially how the mean eccentricity e and inclination i evolve. Mutual gravitational interactions between planetesimals and the Sun are fully taken into account, without any cutoff at “the sphere of influence”. Numerical results in three dimensions show e and i evolve through gravitational interactions toward the state where e ⋍ 2 i , irrespective to the initial conditions.
