Decan 1 · 1–10°
Sub-ruler: Pluto
Double Pluto — the most intense and most private version.
Roughly the first ten days of the sign.
October 23 – November 21 · Water · Fixed · ruled by Pluto (traditionally Mars)
Intensity, privacy and refusal to accept surfaces.
Calculated, not approximated
Every other site prints "October 23 – November 21" with a note that dates "may vary by a day". They vary because the Sun crosses the boundary at a specific moment, and that moment shifts each year — but it is not unknowable.
The figures above are computed: the Sun enters Scorpio when its ecliptic longitude reaches 210°, and that crossing is found to the minute. If you were born near a boundary, this is the answer you actually needed.
Rarely covered
Each sign divides into three ten-degree segments, and each has its own sub-ruler. Two people can both be Scorpio and read as noticeably different because they fall in different decans — roughly, early, middle or late in the sign.
Decan 1 · 1–10°
Double Pluto — the most intense and most private version.
Roughly the first ten days of the sign.
Decan 2 · 11–20°
Softer and more mystical. Intuition over investigation.
Roughly the middle ten days of the sign.
Decan 3 · 21–30°
Emotionally rawer. Feels everything and shows almost none of it.
Roughly the last ten days of the sign.
Sees through pretence instantly and commits completely once convinced.
Tests people rather than asking, and remembers slights for a very long time.
Scorpio is the one fixed water sign — and that pairing is the whole explanation. The element sets temperament: water signs read the room before anyone speaks. The modality decides what happens when circumstances change: fixed signs resist it and hold their position.
There are exactly twelve combinations of four elements and three modalities, and each is occupied by one sign. That is why no two signs are interchangeable, and why Scorpio cannot be swapped for the other water signs without changing the meaning.
Intense, private and observant. Tests before trusting, and remembers the result.
Magnetic and self-contained. Gives access in stages and notices exactly who is paying attention.
Worth saying plainly: nothing in astrology assigns different meanings to a sign by gender. These descriptions reflect how the traits are conventionally written about, not a separate system — and plenty of people will recognise themselves in the other one.
Intense and private. Wants total honesty and gives it slowly.
The friend who turns up in a crisis and never repeats what you told them.
Suited to investigation, research and crisis. Poor at superficial collaboration.
Investigation, research, surgery, psychology, finance — anywhere the surface has to be got past.
Strategic and private about it. Others rarely know the real figure.
Secretive and deeply feeling. Reacts badly to being handled or lied to, even kindly.
Fiercely protective and perceptive. Risks controlling out of fear of loss.
Reproductive and eliminative systems — Scorpio rules them, hence the themes of regeneration.
Ranked by the angle between the two signs on the wheel — the same geometry astrology uses for aspects. Signs 120° apart share an element and form a trine; 90° apart is a square. Nothing here is a matter of opinion.
| With | Aspect | Angle | Score | Element |
|---|---|---|---|---|
| ♋ Cancer | Trine | 120° | 88% | Water |
| ♓ Pisces | Trine | 120° | 88% | Water |
| ♍ Virgo | Sextile | 60° | 82% | Earth |
| ♑ Capricorn | Sextile | 60° | 82% | Earth |
| ♏ Scorpio | Conjunction | 0° | 78% | Water |
| ♉ Taurus | Opposition | 180° | 75% | Earth |
| ♌ Leo | Square | 90° | 62% | Fire |
| ♒ Aquarius | Square | 90° | 62% | Air |
| ♎ Libra | Semi-sextile | 30° | 58% | Air |
| ♐ Sagittarius | Semi-sextile | 30° | 58% | Fire |
| ♈ Aries | Quincunx | 150° | 55% | Fire |

Lists like this are the weakest evidence in astrology and the most quoted. With roughly a twelfth of all people in any sign, every sign has impressive members — picking four of them proves nothing. Read it as trivia, not as support.
October 23 – November 21 as usually published. In 2026 specifically the Sun enters on 23 October am31 09:47 UTC and leaves on 22 November am30 07:29 UTC.
By aspect, Cancer, Pisces, Virgo. Those sit at the easiest angles on the wheel — but sun signs are one factor of many, and a difficult angle describes friction rather than failure.
A ten-degree third of the sign with its own sub-ruler: Pluto, Neptune, Moon. It is why two people of the same sign born three weeks apart can read quite differently.
Reproductive and eliminative systems — Scorpio rules them, hence the themes of regeneration.
Not in the system itself — astrology assigns no gendered meaning to a sign. The separate descriptions above reflect convention in how signs are written about, nothing more.
