[John Carter] What are the planets, from a Martian POV?

We often see in sci-fi stories, like the John Carpenter series, a protagonist drawing a simple solar system to designate where they are from, to a Martian native. But then I thought, "Would Mercury be naked eye visible from Mars?" Followed shortly thereafter, "Would any of the other outer gas giants be visible?"

In short, if a hypothetical Martian was naming wandering stars, or planets, which ones would, or would not, bo on the list?

It should be made clear the civilization we see on Barsoom is basically in its Mad Max phase- a ruined shadow of its once great glory, and life forms are barely kept alive by the atmosphere machines.

So it's possible they had access to better astronomy equipment than "naked eye" at some point in their past

That being said, we do know several names they have given to other planets: they call Mercury "Rasoom," Venus "Cosoom," Earth "Jasoom," Jupiter "Sasoom," and Saturn "Xasoom." Those are in fact all the planets visible to US by naked eye.
