  1. Precession

  2. As the Earth spins, it “wobbles” • Similar to a spinning top or dreidel • One wobble every 26,000 years.

  3. The Changing North Star • Currently, the North Pole (N.P.) points directly towards Polaris (within a degree) • Polaris is not/will not always be the N. Star. • When the pyramids were built, it was a small star called Thubin. • In 12,000 years, it will be a bright star called Vega • Currently there is NO South Star 

  4. Does the N. Star move during the night? • The N. star is the ONLY star that does not appear to move or change positions. • The constellations near Polaris that do not rise or set are called North Circumpolar.

  5. Why did our horoscope signs change? • “Your sign” should be the constellation the Sun was in on the day you were born. • Due to precession (wobble), Earth is not pointing in the same direction it was when astrology was first developed. Thus, your sign has changed!!!

  6. Is astrology science? Ophiuchus- 13th sign of the Zodiac • Astrology is a pseudoscience. Something that appears to be science, but does not follow scientific methodology (i.e. scientific method). • Astrology claims to be able to predict the future by the position of the Sun, stars and planets. • Astrologers have conveniently ignored the 13th sign of the zodiac… Ophiuchus. Poor ophi 
