- Аннотация: In this paper, we present a new approach for solving equations of motion for the trapped motion of the infinitesimal mass m in case of the Elliptic Restricted Problem of Three Bodies (ER3BP) (primaries M_Sun and m_planet are rotating around their common centre of masses on elliptic orbit): a new type of the solving procedure is implemented here for solving equations of motion of the infinitesimal mass m in the vicinity of the barycenter of masses M_Sun and m_planet.Meanwhile, the system of equations of motion has been successfully explored with respect to the existence of analytical way for presentation of the approximated solution. As the main result, equations of motion are reduced to the system of 3 nonlinear ordinary differential equations: 1) equation for coordinate x is proved to be a kind of appropriate equation for the forced oscillations during a long-time period of quasi-oscillations (with a proper restriction to the mass m_planet), 2) equation for coordinate y reveals that motion is not stable with respect to this coordinate and condition y ~ 0 would be valid if only we choose zero initial conditions, and 3) equation for coordinate z is proved to be Riccati ODE of the 1-st kind. Thus, infinitesimal mass m should escape from vicinity of common centre of masses M_Sun and m_planet as soon as the true anomaly f increases insofar.The main aim of the current research is to point out a clear formulation of solving algorithm or semi-analytical procedure with partial cases of solutions to the system of equations under consideration. Here, semi-analytical solution should be treated as numerical algorithm for a system of ordinary differential equations (ER3BP) with well-known code for solving to be presented in the final form.
