摘      要：The double lunar swing-by orbits are a special kind of orbits in the Earth-Moon *** orbits repeatedly pass through the vicinity of the Moon and change their shapes due to the Moon’s *** the synodic frame of the circular restricted three-body problem consisting of the Earth and the Moon,these orbits are periodic,with two close approaches to the Moon in every orbit *** this paper,these orbits are *** is found that these orbits belong to the symmetric horseshoe periodic families which bifurcate from the planar Lyapunov family around the collinear libration point ***,the double lunar swing-by orbits have k=i+j loops,where i is the number of the inner loops and j is the number of outer *** genealogy of these orbits with different i and j is studied in this *** is,how these double lunar swing-by orbits are organized in the symmetric horseshoe periodic families is *** addition,the 2n lunar swing-by orbits(n≥2)with 2n close approaches to the Moon in one orbit period are also studied.
