Horoscope Hang-Up: Earth Rotation Changes Zodiac Signs
If you’re the type of person who relies on mysterious-sounding locations of stars to determine your personality and outcome in life, get ready to be shocked.
The field of astrology, which is concerned with horoscopes and the like, felt a major disruption from astronomers, who are concerned with actual stars and planets. The astronomers from the Minnesota Planetarium Society found that because of the moon’s gravitational pull on Earth, the alignment of the stars was pushed by about a month.

“When [astrologers] say that the sun is in Pisces, it’s really not in Pisces,” noted Parke Kunkle, a member of the group’s board. Your astrological sign is determined by the position of the sun on the day you were born, so that means everything you thought you knew about your horoscope is wrong.
It turns out that astrology has had issues from its inception. (Aside from the fact that it tries to link personality traits with positions of the stars.) Ancient Babylonians had 13 constellations, but wanted only 12, so threw out Ophuchicus, the snake holder. Libra didn’t even enter the picture until the era of Julius Caesar.
