Minnesota Planetarium Society's zodiac claim shot down

Your sign is safe.

Your sign is safe.

Your zodiac sign may be safe after all, no thanks to the Minnesota Planetarium Society.

Its members had horoscope fans frothing over a claim that everything we knew about the zodiac was off by a month. Powerful, obsessive Scorpios were seemingly and suddenly reduced to indecisive, gullible Libras.


The society's Parke Kunkle told the Strib that the zodiac was based on the Earth's position in the constellation, as fixed by ancient Babylonians. Over the centuries, that position has changed, rendering the zodiac outdated -- and in need of an additional sign, Ophiuchus.

But astrologists say that, at least in Western society, there's no need to adjust your tattoos and your pick-up lines. Nothing's changed. And don't panic about having to figure out what being a Ophiuchus is all about. The society was referring to the sidereal zodiac used by the ancient Babylonians -- and many non-Westerners.

Western astrology, on the other hand, is based on what's known as the tropical zodiac; has been since the second century when it was adopted by Ptolemy. The tropical zodiac isn't tied to the constellations. It moves with the seasons. It's flexible.

Did you wake up a Scorpio yesterday and check your horoscope in the local newspaper? Breathe easy. You're not a Libra today.
