The Fleming problem about tides and the Galilei conjectures

The ancient problem of tides, phenomena observed since the humanity early days, still today provides important analysis. In this work, starting with the study of tides, but considering the law gravity, we determine Moon’s characteristics, such as mass, volume, and some aspects of its chemical composition. This approach is carried out by using an inverse-like method, proposed by Henrique Fleming. The formulation provides a way to revisit the Galilei qualitative studies about tides, starting exclusively from the Earth motion. We point out the importance of galilean formulation, what is under criticism in some studies.
