There　are　plentiful　asteroids　moving　periodically　around　their　central　primaries,such　as　the　Sun.Due　to　the　perturbation　of　the　central　primary,the　gravitational　force　of　the　perturbed　asteroid　system　varies　periodically.In　this　paper,based　on　the　idea　of　integrating　the　solar　gravitational　force　as　a　part　of　the　system　instead　of　treating　it　as　perturbation,the　parametric　resonance　response　is　investigated.A　novel　type　of　stable　parametric　resonance　orbits　has　been　detected.It　is　found　that　the　steady-state　motion　amplitude　of　parametric　resonance　orbit　is　determined　by　the　frequency-response　equation.The　stability　of　the　novel　orbits　has　also　been　demonstrated.The　new　type　of　orbits　may　contribute　to　possible　asteroid　exploration　missions.
