Scorpio is the eighth astrological sign in the Zodiac. It spans the 210–240th degree of the zodiac, between 207.25 and 234.75 degree of celestial longitude. Under the tropical zodiac, the sun transits this area on average between October 23 and November 21. Ruled by the all-powerful and seductive Scorpion, Scorpio is perhaps the most misunderstood and mysterious sign of the zodiac. Scorpio is one of the three zodiac signs ruled by the water element. The other two water signs are Cancer and Pisces.
