I so wish that your username had been "Pluto" when you asked that question. Snarkiness put aside, I searched around online to see if maybe I was missing something. It looks like it was simply a misuse of the word. I would have suggested using "celestial body" or even "world" in place of "planet". Perhaps he was using it in the colloquial sense (in the same way a tomato is a "vegetable").
