Sun-sign compatibility · two fire signs · four signs apart

Aries and Sagittarius compatibility

Aries and Sagittarius are four signs apart on the wheel, a trine of about 120°: two fire signs of the same element, one cardinal 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 Aries from 20 March to 20 April and in Sagittarius from 22 November to 21 December. 8 famous couples in StarMap's dataset are an Aries and a Sagittarius, where chance would give about 8.2: Reese Witherspoon and Jake Gyllenhaal, Kim Basinger and Alec Baldwin and Emma Thompson and Kenneth Branagh among them. Among the 537 couples with both Sun signs certain, that makes this the 24th 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: Aries and Sagittarius, with its dates to the minute, its traits and the famous people born under it.

What astrology reads for Aries and Sagittarius

Four signs apart is the trine, and the two signs share an element. Astrology reads this as the easiest angle between Sun signs: each person recognises their own way of running on energy in the other, and the usual translation that two people have to do for each other is mostly unnecessary. The tradition reads trine pairs as the ones who fall into step quickly and keep step without effort.

Ease has a reading of its own. Astrologers note that a trine gives nothing to push against, so a pair can agree their way into a rut, each confirming the other's habits. The tradition treats the angle as a gift that still has to be used, and reads the modality of the two signs, which differs in every trine pair, as where the small useful differences lie.

Fire with fire

Two fire signs are read as two people who both run hot: quick to enthusiasm, quick to act, and happiest when something is happening. The tradition reads the pairing as warm and loud, with more adventures than most and a tendency to burn through plans before either has thought about the next one. Neither is much inclined to be the steady one, and astrologers read the question for a fire pair as who notices when the pace needs to drop.

Cardinal with mutable

A cardinal sign with a mutable one is a starter with an adapter: the tradition describes the pairing as mobile, the cardinal sign choosing the direction and the mutable one fitting around it, and places the strain at the mutable sign's wish to be asked against the cardinal sign's wish to be followed.

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.

Aries in love, Sagittarius in love

Aries

In love, Aries pursues. Interest is shown early and plainly, the chase matters, and the sign is at its best with a partner who can hold their own rather than one who gives way. What it needs to learn is patience: desire arrives before tenderness, and the relationship lasts when the second catches up with the first.

Sagittarius

In love, Sagittarius wants a companion for the road more than a keeper of the house. Freedom matters, so does laughter, and a partner who tries to pin it down usually ends up watching it go. Its lesson is that commitment can be an adventure rather than the end of one.

532 famous people have the Sun in Aries for certain and 449 in Sagittarius: every Aries Sun and every Sagittarius Sun, each with a birth chart.

Famous Aries and Sagittarius couples

Of the 537 spouse and partner pairs in StarMap’s dataset whose Sun signs are both certain, 8 are Aries and Sagittarius. From the share of each sign among every couple’s members, chance alone would give about 8.2, a ratio of 0.98, which makes this the 24th 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.

2 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 four signs apart the way they read the two Suns above, as a trine 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 Sagittarius and the Moon in Aries have pages of their own.

Questions people ask

Are Aries and Sagittarius compatible?

By Sun sign alone, astrology reads Aries and Sagittarius as a trine, four signs apart: two fire signs, cardinal 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 Aries and Sagittarius, against about 8.2 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 Aries and Sagittarius?

8 of the 537 couples in StarMap's dataset with both Sun signs certain, Reese Witherspoon and Jake Gyllenhaal, Kim Basinger and Alec Baldwin and Emma Thompson and Kenneth Branagh among them. Chance alone would give about 8.2, which makes it the 24th 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.

Who has the Sun in Aries and the Moon in Sagittarius?

25 people in StarMap's dataset have the Sun in Aries and the Moon in Sagittarius, Emma Watson, Samuel Beckett and Garry Kasparov among them. 21 people in StarMap's dataset have the Sun in Sagittarius and the Moon in Aries, Sebastián Piñera, Kiefer Sutherland and Ian Somerhalder 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.
