Abstract
Our hypothesis is based on the distribution of approximately circular orbits for terrestrial planets, given by the square law r_n=r_1 n^2, where n's are successive integers starting with n=3 for Mercury, reaching n=6 for Mars and n=8 for Ceres, and r_1 is a constant. Quadratic distribution of orbits is a direct consequence of quantized specific angular momentum. An analysis of the planetary masses, volumes and orbital periods of terrestrial planets, as independent observable parameters, makes possible the statement that the orbit with n=7, between Mars and Ceres was the primordial orbit of the Moon. This statement favours a capture theory of the Moon by the Earth. But why the Moon abandoned its orbit and was captured by the Earth remains a problem for further investigation.
