Domingos, Rita De C. [UNESP]De Moraes, Rodolpho V. [UNESP]De Almeida Prado, A. F.B.2022-04-292022-04-292008-12-01Advances in the Astronautical Sciences, v. 130 PART 2, p. 1571-1578.0065-3438http://hdl.handle.net/11449/231861In the present work, we expanded the study done by Solorzano1 including the eccentricity of the perturbing body. The assumptions used to develop the single-averaged analytical model are the same ones of the restricted elliptic three-body problem. The disturbing function was expanded in Legendre polynomials up to fourth-order. After that, the equations of motion are obtained from the planetary equations and we performed a set of numerical simulations. Different initial eccentricities for the perturbing and perturbed body are considered. The results obtained perform an analysis of the stability of a near-circular orbits and investigate under which conditions this orbit remain near-circular.1571-1578engTrabalho apresentado em evento2-s2.0-60349128402
