Solar system astronomical teaching aid device based on magnetic levitation

The invention discloses a solar system astronomy teaching aid device based on magnetic levitation. The device comprises a supporting base, a circular truncated cone, a plurality of planet model operation structures, a plurality of magnetic levitation bases, a small ball and a levitation magnet, the supporting base is fixedly connected with the circle center of the circular truncated cone, one of the magnetic levitation bases is fixed to the end, close to the circular truncated cone, of the supporting base, and the other magnetic levitation bases are located in the planet model operation structures; the magnetic suspension bases correspond to the small balls with the same number, suspension magnets are arranged in the small balls, the same poles of the suspension magnets and the magnetic suspension bases are opposite, the small balls are suspended above the centers of the magnetic suspension bases, the magnetic suspension bases are located below the circular truncated cone, the small balls are located above th
