A Minnesota astronomer confirms what most people already knew: Your horoscope has been lying to you your entire life. But even those who believe in astrology — that’s 31 percent of Americans, according to a Harris Poll — were duped, because astrologers have apparently been misreading the earth’s alignment because they failed to take the earth’s wobble on its axis.

The Minneapolis Star Tribune speaks to an astronomer who says the moon’s gravitational pull has made the earth wobble on its axis, throwing off zodiac signs as they’re currently understood by about a month.

The Star Tribune reports these are the “true” signs:

Capricorn: Jan. 20-Feb. 16. Aquarius: Feb. 16-March 11. Pisces: March 11-April 18. Aries: April 18-May 13. Taurus: May 13-June 21. Gemini: June 21-July 20. Cancer: July 20-Aug. 10. Leo: Aug. 10-Sept. 16. Virgo: Sept. 16-Oct. 30. Libra: Oct. 30-Nov. 23. Scorpio: Nov. 23-29. Ophiuchus:* Nov. 29-Dec. 17. Sagittarius: Dec. 17-Jan. 20.
* Discarded by the Babylonians because they wanted 12 signs per year.

Thus the Magic 8-Ball remains the most reliable predictor of the future.

Update: CNN talks to astrologers who disagree with the astronomers.
