Which constellation is the extra one traversed by the Sun besides the twelve traditional zodiacal signs?

Answer

Ophiuchus

While the concept of twelve zodiac signs is deeply ingrained in popular culture and astrology, a precise mapping of the current constellation boundaries reveals that the Sun's path along the ecliptic actually cuts across thirteen constellations annually. The extra constellation included in modern astronomical definitions, which is often excluded from astrological consideration, is Ophiuchus, known as the Serpent Bearer. This thirteenth grouping lies along the ecliptic path, meaning the Sun technically passes through its territory during its yearly journey around the sky, leading to the discrepancy between traditional models and current celestial reality.
