Аннотация:In the framework of the restricted three-body problem with orbital commensurability of lower-order mean motions and with an account for the central body's oblateness, the evolution of the apsid line of the passively grabitating point mass is considered. Secular and periodical terms are selected in the obtained analytical expressions. The influence of the oblateness on the variation of the periodical component and of the angular velocity of the apsid line rotation is analysed.
