Would not a planet be classified as having some sort of atmosphere, and if it does not, then would it not be classified as a moon? If a piece of Ice is orbiting a sun with atmosphere than should it not be called a planet, or if a dead planet completely lifeless like our moon, then should it not be classified as a moon? Or simply if the orb has molten lava, then be classified as a planet, then would not our own moon have molten lava within? There still many questions, needed be answered in order to classify any orb in space as a small planet or moon. What if two planets were orbiting eachother, while orbiting some type of gas giant? Would not one be called a moon, or twin planets orbiting eachother, along with their own moons if any? What if a huge asteroid were to orbit a planet, would that be classified as a moon? The possibilities are endless, and may never discover every possibility out there that might exist within the existence of our species concerning planets.
