Commensurabilities are calculated based on published orbital periods of planets and satellites. Examples are given for commensurabilities that are strong or very strong. There are sets of com-mensurabilities that involve 3–4 celestial bodies. Our moon–Earth system is probably a key system forming commensurabilities with all the inner planets. The existence and structure of commensurabilities indicate that all celestial bodies in our Solar System interact energetically…..
