Notes. The top row refers to the basic system (I) including the Sun, the eight planets, and Pluto; below are the more complete systems (II–VI) that have taken into account the effects of individual minor planet populations. The difference Δim between each of the systems II–VI and the system I is presented, and with the displacement Δrb of the solar system’s barycenter accordingly.
