In　this　work,　stability　and　bifurcation　analyses　for　exterior　resonant　orbit　families　have　been　investigated　for　a　test　spacecraft　around　Earth-Moon　system.　The　initial　states　are　obtained　for　certain　resonance　ratio　orbits　in　the　two-body　problem.　The　shooting　method　is　applied　to　compute　the　true　resonant　orbits　families　based　on　the　planar　circular　restricted　three-body　problem.　By　means　of　numerical　approach,　the　1:2　and　2:3　families　of　resonant　orbits　are　studies,　and　the　distribution　of　eigenvalues,　stability　curves　are　presented.　In　particular,　some　critical　points,　corresponding　to　period-doubling　and　tangent　bifurcations,　are　found　in　the　stability　curves.　The　bifurcation　and　stability　analyses　show　overall　features　of　the　resonant　orbits.　This　study　may　provide　alternative　orbital　design　ideas.
