Sul moto ellittico dei pianeti

A didactical approach to the elliptical motion of planets in the solar system is proposed. The planets’ velocities in apsidal points and the total mechanical energy of the two-body systems are discussed and described as functions of orbital parameters. Kepler’s third law is obtained from energy and angular momentum conservation principles.
