equation can be used to describe planetary motion, it must be of great significance. The potential energy in Hamiltonian operator is changed from electromagnetic interaction potential energy to gravitational interaction potential energy, and the Schrödinger equation which can describe planetary motion is successfully obtained. Solving the Schrödinger equation of the earth's revolution is relatively simple, and the energy eigenvalue obtained is completely consistent with the result obtained directly by classical mechanics. The direct significance of establishing and applying this equation is that classical mechanics and wave mechanics can be used to describe all objects at the same time (no longer limited by the mass of objects), which simplifies the calculation process of quantum mechanics. It is proved that classical mechanics and wave mechanics are compatible. The indirect meaning is that it can change the old concept that Schrödinger equation can't be used to describe macroscopic objects.
