Our moon is bigger in size to Pluto, but it is not a planet. What defines a planet?

Our moon’s diameter is 3476 km (Link), which is larger than that of Pluto, which stands at 2370 km (Link). Hence, can our moon be a planet? Answer is yes, if our moon orbits in a circular or slightly elliptical orbit around a star. It is our moon because it orbits around our planet, Earth. … More Our moon is bigger in size to Pluto, but it is not a planet. What defines a planet?
