Highlights

• Evidence for quantized (low-harmonic) planet orbit period ratios.
• Harmonic orbit resonances are a physical model of the empirical Titius–Bode law.
• Exo-planet observations from KEPLER provide statistical tests of model.
• The harmonic orbit resonance model is a self-organization process.

Abstract
The geometric arrangement of planet and moon orbits into a regularly spaced pattern of distances is the result of a self-organizing system. The positive feedback mechanism that operates a self-organizing system is accomplished by harmonic orbit resonances, leading to long-term stable planet and moon orbits in solar or stellar systems. The distance pattern of planets was originally described by the empirical Titius–Bode law, and by a generalized version with a constant geometric progression factor (corresponding to logarithmic spacing).
