Zodiac
The zodiac is an imaginary band in the sky extending about 8 degrees on either side of the ecliptic, divided into 12 equal signs named after constellations, and used in astrology to interpret personality traits and predict events based on the positions of celestial bodies. In astronomy, it serves as a practical coordinate system for tracking the sun, moon, and planets. This ancient framework bridges cultural beliefs and scientific observation, captivating people from horoscope enthusiasts to stargazers.
Did you know?
Due to the Earth's axial precession, which causes the stars to shift over about 26,000 years, the zodiac signs we use today are off by roughly one full sign from their original constellations; for example, if you were born under Virgo, you're actually under Leo's stars. This misalignment, first noted by ancient Greek astronomer Hipparchus around 150 BCE, means that modern astrology doesn't align with the actual sky, yet it still influences billions of people's daily lives.
