Description

What’s your constellation?

The word zodiac derives from a Greek phrase meaning “animal circle,” but it’s initially the Babylonian concept, created in the 5th century B.C. Babylonian astronomers divided the band of the sky where the Sun, Moon, and planets move into equal 12 segments, each occupying 30° of celestial longitude. The segments denoted the 12 equal 30-day months and were given the names we now know as “the zodiac signs.”
