The invention discloses a planetary polishing method adopting magnetic and non-magnetic nano-particle hybrid driving. The method comprises the following steps: adding a liquid solvent, magnetic nano-particles and non-magnetic nano-particles into a container; adopting a mechanical stirrer to stir the mixed solution, thus allowing the solution to flow integrally; applying a rotating magnetic field to the container, wherein a certain angle is formed between the rotating magnetic field and a stirring paddle of the mechanical stirrer, the stirring paddle drives the two kinds of nano-particles to rotate, and meanwhile the magnetic nano-particles do planet-like motion in the driving force direction of the magnetic field; putting a to-be-polished part into the solution, wherein the magnetic nano-particles and the non-magnetic nano-particles collide with the surface of the to-be-polished part in different directions along with flowing of the solution, and thus the effect of grinding and polishing the surface of the to
