Abstract. 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 commensurabilities 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. The Solar System seems to include an unknown physical process capable of transferring energy between both celestial bodies (orbital energy) and between orbital energy and rotational energy. Such a process is proposed to be the major reason for the evolution of commensurabilities, which are judged as not being produced by chance. The physical reason for their creation still remains undiscovered, however.
