[ link to www.urbansurvival.com] Our interest is piqued by a 1999 article in “The Astronomical Journal, 117:1086, 1999 February” where we find (P.3) that indeed, asteroids do have something to do with planet-sized objects, in this case Mars was being discussed, but pay attention to the highlight: “Asteroid perturbations are the largest source of incompletely modeled perturbations of the planets, especially Mars and the Earth-Moon barycenter. Williams (1984) shows no less than seven asteroids capable of making periodic perturbations of more than a kilometer in MarsÏs position. The largest asteroid, Ceres, has only 0.13% the mass of Mars and is located within the asteroid belt itself. Hence, it and the other asteroids are much more sensitive to the perturbations of the asteroids than are the planets. Thus, to achieve high accuracy, the physical model for the asteroid ephemerides must include perturbations by other asteroids.” Hope I'm not breaking any rules my pasting this in here.
