这幅图横跨大约5光年，是在轨道上运行的哈勃空间望远镜于1995年拍摄的。
This picture, spanning about 5 light years, was taken in 1995 by the orbiting Hubble Space Telescope.
最后使用两层微分修正方法将圆型限制性三体问题模型下设计的轨道转换到受摄三体问题模型下。
Finally, the two level differential corrections method was proposed to transform the orbit designed under the circular restricted three-body problem model into the perturbed three-body problem model.
