Thought you were a Scorpion? According to the gradual shift of the earth’s axis over the last 3,000 years and its position in relation to the 12 signs, you’re now under Libra. And oh, yes, there are actually 13!

Astrology buffs all over the world are in a tizzy after learning of a thirteenth sun sign yesterday, along with the fact that changes in the earth’s axis have affected the star sign they are born under.

According to the Washington Post, Minnesota Planetarium Society board member Parke Kunkle announced the existence of the new sign, Ophiuchus, on an NBC TV show.

The constellation Ophiuchus is in the same plane as the other constellations of the zodiac, occurring between Scorpio and Sagittarius — meaning that in Western astrology, people born between November 29 and December 17 now fall under that sign.

So how did all this come about? According to several Western astrologers quoted on the Internet, the existence of Ophiuchus is not a new discovery. The Western astrological chart is derived from that of the ancient Babylonians, who created the star signs by tracking where the sun was in the sky each month. They then got rid of the thirteenth sign to bring the number down to an even 12 over 2,000 years ago.

Kunkle further added that the moon’s gravitational pull has slowly moved the Earth on its axis in the last 3,000 years, creating about a one-month bump in the stars’ alignment. The International Business Times quoted the astronomer as saying, “Because of this change of tilt, the Earth is really over here in effect and the sun is in a different constellation than it was 3,000 years ago.”

In other words, all star signs have changed. According to the ancient Babylonian chart that is followed today, those born between September 23 and October 22 are Librans. If, however, we take into consideration the shift in the earth’s axis over the last two millenia, Libra now falls between October 30 and November 23!
