Why do astronomers think they're right when the 13th zodiac was discovered.?

Ophiuchus was known about by ancient astrologers; it's nothing new.

If there are written down 'rules' for astrologers, a link would be appropriate. If it’s all arbitrary, don’t say astrology has rules.

I noticed the Bill Nye picture. Does that mean you are striving to be science literate? Know the scientific method? Can it be applied to astrology claims?

Read up at the link below especially on the astronomical phenomenon known as the precession of the equinoxes.

Astrology must be twelve sign being a numbers game. Believers like patterns and repetition. Twelve is a very easy number to divide. While if you add or take away one sign, a prime number is the result and no more patterns.

Though the real constellations vary in size, astrologers divided them up into twelve zones of thirty degrees each. For their convenience, not to be accurate. Astrologers don’t boast about their personal accuracy, they do mention customer satisfaction. Well, that’s their say-so. I like to live in an evidence based reality.

FYI, Claudius Ptolemy referenced the constellation Ophiuchus back in the 2nd century AD. So nothing was "discovered." Secondly astronomers, not astrologers, added Ophiuchus to the zodiac they use back in about 1920, i.e. about 99 years ago. As difficult as this simple concept is to grasp, the science Nazis cannot get it through their heads: astronomers do NOT make the rules for the astrologers. Finally, signs and constellations are different things entirely. Therefore the scientists can add or subtract as many constellations as they wish to the zodiac they use and it will have ZERO effect on astrology.

To review:

1) No recent "discovery."

2) The zodiacs used by astronomers and Tropical astrologers are different.

3) Whatever astronomers have to say about the solar system and the ecliptic are irrelevant to astrology.

4) Signs and constellations are different.

I'm quite certain the genius will be here shortly and completely not get it.

EDIT: I was right. Check this out: "If there are written down 'rules' for astrologers, a link would be appropriate"

A link?? Ever heard of an object called a "book?" Go to Amazon and look under "astrology." Bet you never thought of that.

The answer from the genius has nothing to do with the question and is a simple minded cut and paste he or they use anywhere they happen to be on YA.

"Astrology must be twelve sign being a numbers game."

I see your English hasn't improved. There are 12 signs and 12 houses. There are also 12 tribes of Israel. And I know of a family that has 12 children. I guess that's all for easy division. He obviously isn't aware that there was once an 8 sign zodiac and others. He sure doesn't know the precession of the equinoxes, which has nothing at all to do with the question, was discovered over 2000 years ago by <gasp> an astrologer!

>Though the real constellations vary in size, astrologers divided them up into twelve zones of thirty degrees each. For their convenience, not to be accurate. <

Wrong but historical accuracy is about as important to the genius as proper grammar. He possibly finished the 6th grade and STILL doesn't know what a sentence fragment is. The Tropical Zodiac was in place long before the discovery of the precession of the equinoxes. That discovery led to the question of what to do, when the Aries point no longer lined up with the beginning of Aries. Ptolemy answered in his book The Tetrabiblos. He said, more or less, "Ignore it" Astrological signs don't have to line up with the constellations of the zodiac and in fact they never did. So what's the big deal? There is none, but it is impossible to penetrate the concrete between the ears that passes for a skeptic's mind.
