Scorpio
Scorpio is a fixed water sign, traditionally ruled by Mars and, for modern astrologers, by Pluto. It is associated with intensity, loyalty and depth, and with what lies beneath the surface.

In the tradition
Scorpio sits in the middle of autumn, as the year turns toward winter. In Greek myth the scorpion was sent to kill the hunter Orion, and the two were set on opposite sides of the sky so that Orion sets as Scorpio rises. Its brightest star, Antares, is a red supergiant whose Greek name means the rival of Ares, the god the Romans called Mars.
Ptolemy gives Scorpio to Mars. After Pluto was discovered in 1930, many astrologers adopted it as Scorpio's modern ruler. The Moon is in fall here. Traditional authors assigned the sign the genitals, and it has long been linked with sex, death and inheritance.
Strengths and shadows
Scorpio is read as emotional courage. It commits fully, sees through pretense, and is willing to stay with difficult truths that others would rather avoid.
The shadow is control and suspicion. Scorpio can keep score, hold on to resentment, or test people before it trusts them, and its privacy can turn into secrecy.
Scorpio is also read as resilient: a sign that expects to lose things, grieves them fully and comes back changed.
In a birth chart
A planet in Scorpio tends to act with focus and intensity. Mars is at home here. Venus is in detriment and the Moon is in fall, which older authors read as love and feeling made more guarded and more consuming.
Modern astrologers pair Scorpio with the eighth house: shared resources, intimacy, debt, inheritance and change.
