Scorpio and Aquarius compatibility
Scorpio and Aquarius are three signs apart on the wheel, a square of about 90°: water and air, both fixed. Astrology reads the angle between two Sun signs as the first measure of a pair, and the rest of the two charts as the rest of the story.
This year the Sun is in Scorpio from 23 October to 22 November and in Aquarius from 20 January to 18 February. 8 famous couples in StarMap's dataset are a Scorpio and an Aquarius, where chance would give about 8.1: Demi Moore and Ashton Kutcher, Kendall Jenner and Harry Styles and Aishwarya Rai and Abhishek Bachchan among them. Among the 537 couples with both Sun signs certain, that makes this the 25th most common pairing of the 78. A Sun sign is one placement of ten, and the two whole charts say far more than the two signs.
Each sign has its own page: Scorpio and Aquarius, with its dates to the minute, its traits and the famous people born under it.
What astrology reads for Scorpio and Aquarius
Three signs apart is the square, and astrology reads it as friction with a purpose. The two signs share a modality, so both want to act in the same way, by starting, by holding or by adapting, but from elements that do not mix, and each tends to feel that the other is doing the right thing in the wrong manner. The tradition is plain that this angle is felt: these are the pairs that argue about how.
It is also, in the same tradition, the angle that gets things built. Two Suns at a square give each other something to push against, and astrologers read the pairing as one in which both people grow because neither can settle. What the reading asks is that the friction be aimed at the task rather than at each other; the rest of the two charts, the Moons and Venus especially, says how easily that happens.
Water with air
Air with water is read as the thinker and the feeler: one wants to understand the feeling, the other wants it understood. The tradition reads the pairing as curious and tender when it goes well and as two people talking past each other when it does not, since air names what water would rather be felt. Astrologers read it as the pairing in which listening does most of the work.
Fixed with fixed
Both signs are fixed, the signs of the middle of a season, and the tradition reads two fixed people as loyal, stubborn and built to last. Each holds to a position; neither gives way easily. The reading is of a pair that stays once it has decided to, and that may have to be careful which disagreements it decides to keep.
These are readings of the Sun signs alone, written for reflection and entertainment. They describe tendencies the tradition assigns to an angle, not two people, and they do not say whether a pair lasts.
Scorpio in love, Aquarius in love
Scorpio
In love, Scorpio does not do casual well. It wants the whole person and offers the same, and it reads a partner closely enough to be unnerving. Betrayal is not forgiven quickly. Its lesson is that intimacy needs some air, and that loyalty cannot be proved by jealousy.
Aquarius
In love, Aquarius starts from friendship and never quite leaves it. It needs space and conversation, resists possessiveness, and can seem detached when it is simply thinking. Its lesson is that intimacy is not a loss of freedom, and that feelings do not have to be reasonable to be said.
466 famous people have the Sun in Scorpio for certain and 530 in Aquarius: every Scorpio Sun and every Aquarius Sun, each with a birth chart.
Famous Scorpio and Aquarius couples
Of the 537 spouse and partner pairs in StarMap’s dataset whose Sun signs are both certain, 8 are Scorpio and Aquarius. From the share of each sign among every couple’s members, chance alone would give about 8.1, a ratio of 0.98, which makes this the 25th most common pairing of the 78. Their sky match, from the angles between the two charts, averages 58 out of 100 against 67 for every couple counted. With about seven couples a cell, a ratio between a half and double is what chance produces; the counts describe the dataset, not the signs.

Both signs in one chart
The two signs also meet inside one chart, when the Sun is in one and the Moon in the other. Astrologers read a Sun and Moon three signs apart the way they read the two Suns above, as a square between how a person is seen and how they feel.

Questions people ask
Are Scorpio and Aquarius compatible?
By Sun sign alone, astrology reads Scorpio and Aquarius as a square, three signs apart: water and air, both fixed. That is a reading of one placement of ten and not a verdict on two people. In StarMap's dataset of famous couples, 8 are Scorpio and Aquarius, against about 8.1 that chance would give, a ratio of 0.98. The angles between two whole charts, Moon to Moon and Venus to Mars among them, say more than the Sun signs can; the comparison is free on StarMap.
How many famous couples are Scorpio and Aquarius?

Who has the Sun in Scorpio and the Moon in Aquarius?
29 people in StarMap's dataset have the Sun in Scorpio and the Moon in Aquarius, Albert Camus, Shah Rukh Khan and Vivien Leigh among them. 40 people in StarMap's dataset have the Sun in Aquarius and the Moon in Scorpio, Bob Marley, Vladimir Vysotsky and James Dean among them. The Moon's sign depends on the day and often on the hour of birth, so only people whose Moon sign is certain are counted.
Sun signs are computed from the Sun’s position with the astronomy-engine ephemeris, checked against Swiss Ephemeris, in the tropical zodiac. Birth data and relationship data come from Wikidata; birth times, where StarMap has one, from Astro-Databank with their Rodden rating. A couple is counted only when the Sun was in one sign for the whole of each birth date. Readings describe what the tradition assigns to an angle, for entertainment and self-reflection; StarMap predicts nothing. Compare two whole charts.
