I know that exists an original work of Walter Murch on planetary orbital quantization on same way of the electron orbital quantization.
Unfortunately the author has not publicized never his job on the web but only in astrophysical lectures, for which I have not succeeded in finding something on Google on the modification of Murch of the original Titius-Bode formula.
Only exception this passage from the site of Halton Arp:
"Shortly afterward O. Neto, Agnese and Festa, L. Nottale and A. and J. Rubcic independently in Brazil, Italy, France and Croatia began pointing out similarities to the Bohr atom in the orbital placement of the planets. Different variations of the Bohr-like radius = n² or n² + 1/2n fits the planetary semimajor axes extremely well with rather low quantum numbers n. Most recently I have learned of to modification to the Titius-Bode law by Walter Murch where the planetary radii = 1 + 2^n + 2^n-1".

To me it seems very interesting this possible relationship of electric nature related to the circolarization and stability of the planetary orbits as it happens for the atomic nucleus.
