Major (exo)planetary and satellite bodies seem to concentrate at intermediateareas of the radial distributions of all the objects present in each(sub)system. We prove rigorously that the secular evolution of (exo)planets andsatellites necessarily results in the observed intermediate accumulation of themassive objects in all such subsystems. We quantify a "middle" as the mean ofmean motions (orbital angular velocities) of three or more massive objectsinvolved. Orbital evolution is expected to be halted or severely diminishedwhen the survivors settle near mean-motion resonances and substantialangular-momentum transfer between bodies ceases to occur (gravitational Landaudamping). The dynamics is opposite in direction to what has been theorized forviscous and magnetized accretion disks in which gas spreads out and away fromeither side of any conceivable intermediate area. The results are bound tochange the way we think about planet and moon formation and evolution.
