In this paper we use the BCP to study the existence of Halo-like orbits around $L_{2}$ in the Earth-Moon system taking into account the perturbation of the Sun. By means of computing families of 2D invariant tori, we show that there are at least two different families of Halo-like quasi-periodic orbits around $L_{2}$.application/pdfeng(c) Springer Verlag, 2021Mecànica orbitalAstrofísicaProblema dels tres cossosOrbital mechanicsAstrophysicsThree-body probleminfo:eu-repo/semantics/article7201932022-02-25info:eu-repo/semantics/openAccess
