Capricorn and Aquarius compatibility

Capricorn and Aquarius are one sign apart on the wheel, a semi-sextile of about 30°: earth and air, one cardinal and one 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 Capricorn from 21 December to 20 January and in Aquarius from 20 January to 18 February. 11 famous couples in StarMap's dataset are a Capricorn and an Aquarius, where chance would give about 8.1: Ronald Reagan and Jane Wyman, Cristiano Ronaldo and Irina Shayk and Nicolas Cage and Laura Dern among them. Among the 537 couples with both Sun signs certain, that makes this the 7th 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: Capricorn and Aquarius, with its dates to the minute, its traits and the famous people born under it.

What astrology reads for Capricorn and Aquarius

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.

Earth with air

Earth with air is read as the practical sign and the thinking sign: one asks what works, the other asks why. The tradition reads the pairing as civil and often productive, each supplying a competence the other lacks, and cooler than most, since neither element leads with feeling. The reading is that these two can build a good life together and may need to remember to enjoy it.

Cardinal with fixed

One sign is cardinal and one is fixed: a starter and a keeper. The tradition reads the pairing as complementary, the cardinal sign supplying new directions and the fixed sign holding to the ones worth keeping, and as a contest when the one that starts wants to start again and the one that holds has only just settled.

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.

Capricorn in love, Aquarius in love

Capricorn

In love, Capricorn is slow, careful and then constant. It shows commitment by showing up, year after year, and it finds romance easier to practise than to declare. Its lesson is that a partner wants to be let in, not only provided for.

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.

468 famous people have the Sun in Capricorn for certain and 530 in Aquarius: every Capricorn Sun and every Aquarius Sun, each with a birth chart.

Famous Capricorn and Aquarius couples

Of the 537 spouse and partner pairs in StarMap’s dataset whose Sun signs are both certain, 11 are Capricorn and Aquarius. From the share of each sign among every couple’s members, chance alone would give about 8.1, a ratio of 1.35, which makes this the 7th most common pairing of the 78. Their sky match, from the angles between the two charts, averages 68 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.

5 more on the couples page. All famous couples, each scored from both birth charts.

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.

Only people whose Sun and Moon signs do not depend on an unknown birth time are counted. The Moon in Aquarius and the Moon in Capricorn have pages of their own.

Questions people ask

Are Capricorn and Aquarius compatible?

By Sun sign alone, astrology reads Capricorn and Aquarius as a semi-sextile, one sign apart: earth and air, cardinal with fixed. That is a reading of one placement of ten and not a verdict on two people. In StarMap's dataset of famous couples, 11 are Capricorn and Aquarius, against about 8.1 that chance would give, a ratio of 1.35. 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 Capricorn and Aquarius?

Who has the Sun in Capricorn and the Moon in Aquarius?

22 people in StarMap's dataset have the Sun in Capricorn and the Moon in Aquarius, Muhammad Ali, Denzel Washington and Salman Khan among them. 15 people in StarMap's dataset have the Sun in Aquarius and the Moon in Capricorn, Ayn Rand, Ángel Di María and Emma Roberts 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.
