Your REAL Zodiac Sign - INAOE

The astronomy behind astrology

  • Do you know that what you consider to be your zodiac sign, might not be correct?
  • Do you know that since the invention of the zodiac system more than 3000 years ago, the sky has actually changed and the traditional zodiac signs do not correspond to the actual ones?

In this page, I try to give a scientific explanation to these questions and on the way, let you discover your real zodiac sign. I start by introducing some astronomical concepts which I hope will give you some insight about the geometry and the physics of the rotation of the Earth around the Sun and the apparent movement of the objects on the sky. I like to point out that the main purpose of this page is to show the astronomical facts behind what we call zodiac signs, and I just did it for fun! (after all, being an astronomer I am always asked about other people's horoscopes!). It is not my intention to discuss in depth the validity of astrology or its predictions, however I give my personal opinion as an astronomer, if you're interested.
