Scorpio is the eighth astrological sign in the Zodiac, originating from the constellation of Scorpius. In western astrology the sign is no longer aligned with the constellation as a result of the precession of the equinoxes. Scorpio is considered a "feminine" and "fertile", negative (introverted) sign by most modern astrologers. It is also considered a water sign and one of the four fixed signs. Traditionally, the planet Mars has been considered to be the ruler of Scorpio. Also, since its discovery, Pluto has been considered a modern ruler of this sign. As the eighth sign in the zodiac, Scorpio is associated with the astrological eighth house.
Individuals born when the Sun is in this sign are considered Scorpio individuals. Under the tropical zodiac, the Sun enters Scorpio around October 23 and exits around November 22. Under the sidereal zodiac, it is currently there roughly from November 16 through December 15. The Sanskrit name of Scorpio in Hindu astrology is Vrścika.
Based on Elements within the Zodiac, Scorpio is considered compatible with Pisces and Cancer.
There are many variables that determine compatibility in astrology, such as birth dates, birth months, birth years, position of a sign within the Sun, the Moon, Stars, etc. The signs listed as compatible with Scorpio do not reflect an individual profile or individual reading as interpreted within astrology. They instead reflect a general guideline and reference to compatibility as dictated by variables such as Qualities and Elements within the Zodiac. The branch of astrology dealing with interpersonal compatibilities is called Synastry.
