I think the word came from Greek, meaning "Wanderer" and was used to refer to the plantes visible before Telescopes were invented. By that definition, Saturn is the furthest-most planet; everything else is not visible to the unaided eye.

You are correct. The classical planets (which include the sun and the moon) are called that because they "wander" across the sky against the background of fixed stars.
