摘要：

In this paper we investigate orbits of a spacecraft in the vicinity of libration points (L-points) in the Earth-Moon system. For the gravitational potential we consider Rein's semi-averaging method in the planar elliptic restricted three-body problem (ERTBP) and compute higher order power series of this function in terms of the eccentricity. Then we analyze the precision of various orbits around each libration point, for different orders of the potential function power series. We find that for accurate orbits closer to the L-2-point one needs a higher order approximation. We illustrate our results by generating more accurate orbits around the L-points in the Earth-Moon system and compare them to previous results in the literature.
