Аннотация:A developing approach for solving equations of a trapped motion of small satellite near the secondary planet m_planet (Earth) in case of the elliptic restricted problem of three bodies, ER3BP, is presented hereby. In ordinary way, this problem includes consideration of two primaries, M_Sun and m_planet (m_planet < < M_Sun), both are orbiting around their center of mass on Keplerian orbits. Eccentricity of orbit for the aforementioned m_planet is considered to be quasiperiodically variable depending on long-term Milankovitch cycles or various types of seasonal irradiation processes influencing onto orbit of planet (hereafter, Earth). Our aim is first to establish and second to investigate a novel type of ER3BP with variable eccentricity of secondary planet stemming from long-term Milankovitch cycles where in the formulation of above problem, small satellite will always maintain its orbit located near the secondary planet, m_planet. Indeed, Milankovitch cycles govern the dynamics of slow changing the eccentricity of the secondary planet orbit quasiperiodically during a long-time period of secondary planet's motion around the primary. This planet moves on quasi-stable elliptic orbit with negligible deviations from purely elliptical motion. Semi-analytical solutions and numerical findings with graphical plots are presented accordingly.
