Libra and Sagittarius compatibility
Libra and Sagittarius are two signs apart on the wheel, a sextile of about 60°: air and fire, 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 Libra from 23 September to 23 October and in Sagittarius from 22 November to 21 December. 11 famous couples in StarMap's dataset are a Libra and a Sagittarius, where chance would give about 8.9: Brad Pitt and Gwyneth Paltrow, Taylor Swift and John Mayer and Édith Piaf and Yves Montand among them. Among the 537 couples with both Sun signs certain, that makes this the 6th 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: Libra and Sagittarius, with its dates to the minute, its traits and the famous people born under it.
What astrology reads for Libra and Sagittarius
Two signs apart is the sextile, and astrology reads it as the angle of easy conversation. The signs belong to elements that feed each other, fire with air or earth with water, so the two people tend to want compatible things without wanting the same thing. The tradition reads the pairing as friendly first: it is the angle most often found between people who liked each other before anything else was decided.
Because the sextile asks little, it is also the angle the tradition says can be left to drift. There is no friction to work against and no mirror to look into, so the relationship tends to be as warm as the attention it is given. Astrologers read it as an opportunity rather than a pull, and look to the rest of the two charts for whatever holds the pair together when the conversation stops.
Air with fire
Fire with air is read as the pairing that feeds itself: air gives fire room to burn and fire gives air something to be excited about. The tradition reads these two as talkative, restless and fast, good company for each other and inclined to keep moving rather than settle. The reading's question is where the stillness comes from, since neither element supplies much of it.
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.
Libra in love, Sagittarius in love
Libra
In love, Libra is made for partnership and knows it. It is attentive, considerate and romantic, and it can lose itself in the other person while trying to keep the peace. Its lesson is that a relationship with two whole people in it is more balanced than one with one person bending.
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.
517 famous people have the Sun in Libra for certain and 449 in Sagittarius: every Libra Sun and every Sagittarius Sun, each with a birth chart.
Famous Libra and Sagittarius couples
Of the 537 spouse and partner pairs in StarMap’s dataset whose Sun signs are both certain, 11 are Libra and Sagittarius. From the share of each sign among every couple’s members, chance alone would give about 8.9, a ratio of 1.23, which makes this the 6th 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 two signs apart the way they read the two Suns above, as a sextile between how a person is seen and how they feel.

Questions people ask
Are Libra and Sagittarius compatible?
By Sun sign alone, astrology reads Libra and Sagittarius as a sextile, two signs apart: air and fire, 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, 11 are Libra and Sagittarius, against about 8.9 that chance would give, a ratio of 1.23. 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.

Who has the Sun in Libra and the Moon in Sagittarius?
29 people in StarMap's dataset have the Sun in Libra and the Moon in Sagittarius, Zlatan Ibrahimović, Mesut Özil and Naomi Watts among them. 23 people in StarMap's dataset have the Sun in Sagittarius and the Moon in Libra, Walt Disney, Jay-Z and Michael Owen 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.
