[en] The main directions of modern planetogonic theories are reviewed shortly and confronted with 'reconstruction characteristica' which have to be fulfilled by every realistic planetogonic theory. It is especially the existence of comparable structures in the four satellite systems of Sun, Jupiter, Saturn and Uranus which indicates the action of structuring large-scale collective gravitational instabilities in the preplanetary disk. The resulting planetogonic scenario is able to explain the observed radial structures in the four systems (and to formulate correct predictions). Properties of the preplanetary disk are derived from this scenario. (author)
