The invention discloses a spin nutation coupling racemization plume pointing method and system based on plume racemization, and belongs to the technical field of spacecrafts, and the method comprises the steps: collecting the rotational inertia and angular velocity data of a target in a motion state; counting spinning-nutation racemization torque parameters capable of being received by the target solar panel in the racemization process; inputting the spin-nutation racemization torque parameter, the rotational inertia and the angular velocity data into a coupling racemization plume pointing model to obtain an optimal plume pointing point; and inputting the optimal plume pointing point into the plume racemization kinetic model for racemization calculation to obtain a racemization termination condition, and if the motion state of the target meets the racemization termination condition, completing the racemization task. According to the method, spin nutation coupling racemization of the target can be achieved according to the motion characteristic, the quality characteristic and the shape characteristic of the target, the problem that the racemization guidance law is insufficient is solved, and the method is suitable for various racemization modes in which a failure satellite solar panel is used for generating resistance torque.
