Titius - Bode law
There is proposed a hypothesis according to which the regular structure of planetary and satellites systems can be explained as a consequence of spatially periodic condensation of gaseous matter during the formation of the Central Body.
According to the hypothesis, the periodic condensation on cosmic scales is analogous to the Liesegang phenomenon. Calculations indicate that the hypothesis is in agreement with certain facts: the mechanism of condensation under consideration does not contradict the basic laws of diffusion (mass transfer) and s number of physical models:

Now the Titius-Bode law sometimes helps to find new exoplanets!
According to the model Saturn is younger Earth. Titan is younger than Saturn! See also: http://creatacad.org/?id=23&lng=eng !
The violation of law may be in the latter stages of the evolution of planetary and satellite systems as a consequence of the action of gravitational forces.
