CHAPTER THIRTEEN. THE “RULE OF EIGHT” IN THE COSMOS. PLANETARY ORBITAL VELOCITIES.
The ratios between planetary orbital velocities tend to be multiples of ONE EIGHTH. There is absolutely no logical reason why this should be so. The laws of physics cannot explain why it happens. Iohannes Kepler was the first person to notice this fact. What he actually said was that the ratios between planetary orbital velocities mimic the ratios of the musical (diatonic) scale, which, as we have already seen, are (all but one) perfect multiples of one EIGHTH.
Here are just a couple of examples involving Earth and (its neighbour planet) Mars.
Mars’ orbital velocity at aphelion is almost exactly six EIGHTHS of Earth’s orbital velocity at aphelion; and Mars’ orbital velocity at perihelion is almost exactly seven EIGHTHS of Earth’s orbital velocity at perihelion.
Now I will go into this feature in detail.
