Aquarius and Pisces compatibility
Aquarius and Pisces are one sign apart on the wheel, a semi-sextile of about 30°: air and water, one fixed and one mutable. 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 Aquarius from 20 January to 18 February and in Pisces from 18 February to 20 March. 8 famous couples in StarMap's dataset are an Aquarius and a Pisces, where chance would give about 6.4: Justin Timberlake and Jessica Biel, Taylor Lautner and Lily Collins and Paul Newman and Joanne Woodward among them. Among the 537 couples with both Sun signs certain, that makes this the 32nd 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: Aquarius and Pisces, with its dates to the minute, its traits and the famous people born under it.
What astrology reads for Aquarius and Pisces
Signs next door to each other share nothing by element or by modality, and astrology reads neighbouring Sun signs as two people who grew up on either side of a fence: close enough to see each other every day, far enough apart to have learnt different lessons. The later sign is traditionally taken to have been shaped by what the earlier one left unfinished, so each tends to be good at what the other finds hardest.
The reading is of a pairing built on difference rather than likeness. There is little automatic understanding to fall back on, and more to find out, which some people find restful and others find like work. Astrologers often say these pairs make each other more complete than comfortable: the relationship is where each learns the step that comes next in the zodiac.
Air with water
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 mutable
One sign is fixed and one is mutable, a keeper with an adapter. In the tradition the fixed sign gives the relationship its shape and the mutable sign its give; the strain is read as each mistaking the other's nature for a choice, the fixed sign taking flexibility for drift and the mutable sign taking steadiness for refusal.
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.
Aquarius in love, Pisces in love
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.
Pisces
In love, Pisces is devoted, romantic and quick to merge. It idealises a partner, forgives too readily, and can lose track of where it ends and the other begins. Its lesson is that boundaries are a form of love too, including love of itself.
530 famous people have the Sun in Aquarius for certain and 520 in Pisces: every Aquarius Sun and every Pisces Sun, each with a birth chart.
Famous Aquarius and Pisces couples
Of the 537 spouse and partner pairs in StarMap’s dataset whose Sun signs are both certain, 8 are Aquarius and Pisces. From the share of each sign among every couple’s members, chance alone would give about 6.4, a ratio of 1.26, which makes this the 32nd most common pairing of the 78. Their sky match, from the angles between the two charts, averages 67 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 one sign apart the way they read the two Suns above, as a semi-sextile between how a person is seen and how they feel.

Questions people ask
Are Aquarius and Pisces compatible?
By Sun sign alone, astrology reads Aquarius and Pisces as a semi-sextile, one sign apart: air and water, fixed with mutable. 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 Aquarius and Pisces, against about 6.4 that chance would give, a ratio of 1.26. 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 Aquarius and Pisces?
8 of the 537 couples in StarMap's dataset with both Sun signs certain, Justin Timberlake and Jessica Biel, Taylor Lautner and Lily Collins and Paul Newman and Joanne Woodward among them. Chance alone would give about 6.4, which makes it the 32nd most common pairing of the 78. Their sky match, from the angles between the two charts, averages 67 out of 100 against 67 for every couple counted.
Who has the Sun in Aquarius and the Moon in Pisces?
28 people in StarMap's dataset have the Sun in Aquarius and the Moon in Pisces, Neymar, Charlotte Rampling and Dick Cheney among them. 35 people in StarMap's dataset have the Sun in Pisces and the Moon in Aquarius, Hebe Camargo, Bruce Willis and Miriam Makeba 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.
