Would depend on the context, I think. If European, Byzantian or Arabic, the system would be Ptolemy's. If Indian or Chinese, would be the system adopted by those civilizations. But I guess it would not differ in the number of planets, since indeed, as noted above, those are the celestial bodies visible with naked eye. Might well differ in the number of stars, though.
