Starting from a previously stated hypothesis concerning the discretization of the orbits for periodic celestial motions, the mass of ups-Andromedae and the periods of its b- and d- companions are estimated using the accurately known period of the massive c-companion. Moreover, the periods and the orbital major semiaxes of other hypotetically existing and not yet discovered smaller planets of ups-Andromedae are guessed.
