Abstract: Background and characteristics of interplanetary superhighway are presented in this paper. The circular restricted three-body problem and its periodic orbit and quasi-periodic orbit are analyzed. Application of interplanetary superhighway technology in the satellite Kuafu-A is discussed. At last its potential merits in the exploration of future deep-space exploration activities are discussed.

Key words: interplanetary superhighway, libration point, circular restricted three-body problem, halo orbit, manifold
