Scorpio

Definition

Scorpio is the eighth sign of the zodiac, covering 210 to 240 degrees of the ecliptic — the circle the Sun appears to travel over a year. It is a fixed water sign, traditionally ruled by Mars; modern Western astrology often adds Pluto as a co-ruler. The Moon is in fall (weakened) here. The Sun moves through Scorpio from roughly October 23 to November 21 each year. Scorpio reads as feminine in the odd/even polarity scheme, and it belongs to the water triplicity alongside Cancer and Pisces. Hellenistic astrology called the fixed signs sterea, meaning "solid."

In Tradition

Astrologers in the Western tradition link Scorpio with emotional intensity, transformation, and a willingness to face what lies hidden. The sign is traditionally tied to themes of power, secrecy, and regeneration.

In Practice

In a birth chart, astrologers read Scorpio placements when looking at emotional intensity, how deeply someone engages psychologically, and a capacity for real change. The Moon's fall in Scorpio is noted in dignity assessments — the weighing of a planet's strength by sign — as a traditionally weakened position for the Moon. Because Mars rules Scorpio, placements here connect to themes of penetrating action and a steady, sustained emotional drive. As planets transit, or pass through, Scorpio, they tend to bring intensity, depth, and a reckoning with what has been concealed. In horary astrology — answering a specific question from a chart cast for the moment it is asked — a strong showing of fixed signs suggests conditions that are dug in and slow to shift.

Historical Origin

Scorpio appears as one of the twelve zodiacal signs in the earliest Hellenistic texts. Hellenistic sources record Scorpio as a fixed (sterea) sign of the water triplicity. Mars's rulership of Scorpio is part of the symmetrical scheme that assigns each planet the signs it rules. In medical astrology, the body region matched to Scorpio is the reproductive organs.
