Abstract

In the paper is shows that the Titius-Bode relation of the distances Sun-planet may be explained by a Kant-Laplace type model of planetary system forming, considering a linear decreasing of the lenticular protoplanetary nebula’s density and the constancy of its rotation speed. The resulted conclusions is that the protoplanetary material rings were formed by the successive halving of the nebular mass M_N and thereafter- of the remained part and may be generalized for the star clusters, for the galaxies forming but also for the expansion of the galaxies super-clusters and of the Universe.
