Leo and Leo compatibility
Two Leo Suns are a conjunction by sign: the same element, fire, the same modality, fixed, and the same month of the year. Astrology reads the same sign as the angle of likeness, and the pairing as the one in which two people recognise themselves in each other first.
This year the Sun is in Leo from 22 July to 23 August, so both people were born in the same few weeks of the year, in whatever years. 5 famous couples in StarMap's dataset are two Leo Suns, where chance would give about 4.5: Madonna and Sean Penn, Jennifer Lopez and Ben Affleck and Charlize Theron and Sean Penn among them. Among the 537 couples with both Sun signs certain, that makes this the 62nd 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: Leo, with its dates to the minute, its traits and the famous people born under it.
What astrology reads for Leo and Leo
Two people with the Sun in the same sign share a way of being seen. Astrology reads the Sun as the part of a person that wants to be recognised, and when two Suns sit in one sign each already understands what the other is asking for: the same kind of praise, the same kind of attention, the same idea of what a good day looks like. The first weeks tend to feel like being understood without explaining.
The tradition is also candid about the cost. What two people share they also compete over, and a pair with the same Sun sign can find that the thing they both want most is the thing there is only one of in the room. The reading is that the sign's strengths are doubled and so are its blind spots, and that the rest of the two charts, the Moons and the rising signs above all, decides whether the likeness feels like company or like a mirror.
Two fire signs
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.
Two fixed signs
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.
Leo in love
Leo
In love, Leo is romantic in the old sense: grand gestures, open admiration, a wish to be adored and to adore back. It needs appreciation the way other signs need space. Its lesson is that affection shown quietly counts too, and that a partner is not an audience.
520 famous people have the Sun in Leo for certain: every Leo Sun, each with a birth chart.
Famous Leo and Leo couples
Of the 537 spouse and partner pairs in StarMap’s dataset whose Sun signs are both certain, 5 are two Leo Suns. From the share of each sign among every couple’s members, chance alone would give about 4.5, a ratio of 1.12, which makes this the 62nd most common pairing of the 78. Their sky match, from the angles between the two charts, averages 78 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.

Questions people ask
Are two Leo Suns compatible?
By Sun sign alone, astrology reads two Leo Suns as a conjunction: the same element and modality, with the sign's strengths doubled and its blind spots too. That is a reading of one placement of ten and not a verdict on two people. In StarMap's dataset of famous couples, 5 are two Leo Suns, against about 4.5 that chance would give, a ratio of 1.12. 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 two Leo Suns?
5 of the 537 couples in StarMap's dataset with both Sun signs certain, Madonna and Sean Penn, Jennifer Lopez and Ben Affleck and Charlize Theron and Sean Penn among them. Chance alone would give about 4.5, which makes it the 62nd most common pairing of the 78. Their sky match, from the angles between the two charts, averages 78 out of 100 against 67 for every couple counted.
Who has the Sun and the Moon both in Leo?
27 people in StarMap's dataset have the Sun in Leo and the Moon in Leo, Halle Berry, Charlize Theron and Peter O'Toole 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.
