It is equal to 0 when the body is at the pericenter, π radians (180°) at the apocenter, and 2π radians (360°) after one complete revolution. Trecerea lui Jupiter prin periheliu nu poate fi gasita printr-o relatie liniara datorita perturbatiei pe care o exercita Saturn. Jupiter si Saturn sunt intr-o (aproximativa) rezonanta, cinci perioade de revolutie ale lui Jupiter echivaland cu doua ale lui Saturn.
