Abstract : This report deals with some theoretical investigations on trajectories of the twobody problem in Celestial Mechanics. Specifically, consideration is given elliptic trajectories having the same attracting focus and corresponding to a fixed value of the total energy. The purpose of the report is twofold: (a) to find the envelope curve for the planar system of elliptic trajectories passing through a fixed point, (b) to determine which one of the two trajectories passing through two fixed points yields a 'strong' minimum for the action integral in the sense of the calculus of variations.
