Earth’s axial precession shifts zodiac signs from original constellations
Zodiac signs most people know today no longer align with the actual constellations due to Earth's axial precession, unequal constellation sizes, and the existence of a 13th constellation, Ophiuchus.
Why it matters: The tropical zodiac used in Western astrology is based on star positions from 2,000 years ago, not current astronomical reality.
The big picture: Astrology and astronomy once overlapped but have diverged, with astrology adapting to cultural trends despite lacking scientific support.
Stunning stat: The sun spends over twice as long in Virgo as in Cancer, showing uneven constellation sizes ignored in traditional zodiac signs.
Commenters say: Many discuss the historical reasons for the zodiac's structure, question astrology's validity, and find the inclusion of Ophiuchus intriguing.
