There is proposed an hypothesis according to which theregular structure of planetary systems can be explained as a consequenceof spatially periodic condensation of gaseous matter during the formationof the Central Body.
According to the hypothesis, the periodic condensationon cosmic scales is analogous to the Liesegang phenomenon. It has beenestablished that, using the theory of supersaturation, one can explainthe nature of the law, where is the major semi-axis of the n-th orbit, and and areconstants.
Calculations indicate that the hypothesis is in agreementwith certain facts: the mechanism of condensation under consideration doesnot contradict the basic laws of diffusion and s number of physical models:
It is argued that diffusion of matter into the Nebulacould have occurred from the Sun or from peripheral regions of the SolarSystem.
