A test platform for weak gravitational star catalogue touch sampling test relates to the technical field of deep space exploration and comprises a support, a Stewart platform, a transverse frame, a vertical frame, a cable, a pulley, a motor, a counterweight, a detector simulator, a sampling execution mechanism, a sampler, a star catalogue simulation medium, a laser tracker and a target. Full-motion-degree-of-freedom weak gravitation simulation of the detector can be realized, and touch sampling simulation of the detector and a detector state inversion test in the touch sampling process can be realized; weak gravity simulation on the surface of a small celestial body can be realized, and microgravity simulation on the surfaces of the moon, the Mars and the like can also be realized; the motor improves the weak gravitation simulation precision of the test platform and the reaction speed of the test platform through active control, the pose and speed of the detector during sampling can be realized without controlling the detection simulator, and the test difficulty is reduced.
