On a macroscopic level, the orbital states do exist for satellites orbiting Earth but are too closely spaced for us to see. On a macroscopic level, the orbital states do not exist for satellites orbiting Earth. On a macroscopic level, we cannot control the amount of energy that we give to an artificial satellite and thus control its orbital altitude.
