On Star Wars and derivations... Bertram Thomas' Arabia Felix, about his crossing of the Empty Quarter, listed some names of stars, transliterated from the arabic.

The north star, was written as Al Jedi... the Jedi. It goes a step further, in that it's arabic which translates as the kid (as in a goat, but the same way Hans refers to Luke).

I'm not sure how much is coincidence, but reading about Thomas preparing to travel by starlight, it struck me as being remarkably reminiscent. I guess there are no original stories.
