I reckon a planet is anything bigger than Uranus.

Now hang on a sec, If a planet is an orbiting body, then how big is the body of the gas giants?? You can not include gas as the body. Could be they are smaller than pluto, geeeez, back to the drawing board. Wait, I have it, they must be palnetry nebula. Iv'e come full circle, or is that an orbit?

Reading between the lines of my posts, can you tell I just dont take this argument seriously? What a nonsense.
