Figure 3: The quasi-periodic trajectories near , , , and created by STK with the epoch time of 12:00, July 1, 2015. The bounded trajectories are shown in (a) the syzygy frame in Earth-Moon system and (b) the Earth-centered inertial frame. The ground tracks of the trajectories are shown in (c) the Earth-centered fixed frames and (d) the Moon-centered fixed frames.
