The Torah seems to have many examples where astrology is deemed real. (such as the astrology predictions that Moshe would be struck by water which made Paraoh throw the jewish males in the nile river. Or the midrash that says Avraham could see through astrology that he would not have children.)

What does Judaism say about the efficacy of astrology? Do Jews believe that astrology is real, or that it is just a bunch of coincidences?

"The official Torah position" what does that mean? –  Double AA Jul 12 '13 at 8:29
the majority opinion from the reliable sources –  ray Jul 12 '13 at 8:38
That's quite a non traditional definition –  Double AA Jul 12 '13 at 12:07
@msh210...he says pretty clearly that the Torah apparently deems it real, not that the Torah says so definitively. –  Yirmeyahu Jul 12 '13 at 20:54
@DoubleAA, ado you take issue that there is an "official Torah position" on anything and if not what is the problem if the questioner asks if ther is such a position on this topic? –  Yirmeyahu Jul 12 '13 at 20:56

Definitely it is real. See Masheches Shabbas 156: go through the whole gemara there, starting with where it says "Rabbi Yehoshua Ben Levi". It indicates that the day and time of someone's birth can affect him, though that there is a dispute as to whether Israel is affected by it.

Just because it is in the gamoro doesn't mean it is really that way. –  MoriDoweedhYaa3qob Jul 14 '13 at 2:03
Please explain,don't know what you mean? –  sam Jul 14 '13 at 2:32
rambam says that in the gamoro's times people followed the sciences and the ideas of the time. astrology was a big part in that time period. however, it does not mean that astrology is true. –  MoriDoweedhYaa3qob Jul 14 '13 at 4:45

See Does the Zodiac really have influence on our lives? where the view of the Rambam in his letter on astrology is discussed. To summarize, Rambam is of the opinion that astrology is ineffective and that sages who appear to have believed in it were either mistaken or speaking non-literally.
