Using your standard of measure, thus far the eyebrow-raiser would be Enoch fragment 4Q204 which appears to be carbon dated about 180 B.C.
I'm searching for more information, but the anamoly is that orbits were not proposed by the Greeks until 150 B.C. coupled with the fact that the Enoch manuscript is a copy from a source of unknown antiquity.
Finally, there are fragments just now being made available for carbon dating - so more questions may arise.
(That's a paraphrase of what I've found thus far; I will try to find quality links and excerpts to back it up.)
Again, the context is that the Greeks proposed orbits at 150 B.C. and the Qumran text is a copy in Aramaic from an orginal of unknown antiquity but seemingly originating from Judea.
I'm pinging others who may be following the discussion and thus, might want to check out the link.
