Do famous couples have compatible signs?
Not by Sun sign alone. Their Sun signs match as often as random pairs would.
The usual Sun-sign rule says a sign gets on with its own element, and fire with air, earth with water. That is six signs of the twelve for anyone, so half of all couples land on a match by chance alone. Famous couples land on one just as often: 365 of 727.
The Sun is one planet of ten. An astrologer reads the rest: the Moon, Venus and Mars, and how two whole charts meet.
No match on paper, together for years
By that rule, each pair’s Sun signs miss. Each has been together 10 years or more.

Do matched couples last longer?
No. Of the couples still together, 48% have signs said to get on. Of the couples who split, 50%. Random pairs of the same people give half either way.

The full count
How far apart their Suns stand
Each couple by how many signs separate the two Suns, round the shorter way. The mark is chance: the same people, partners dealt at random two thousand times.
- The same sign69, chance gives 60
- Next door122, chance gives 122
- Two apart109, chance gives 123
- Three apart123, chance gives 120
- Four apart123, chance gives 120
- Five apart117, chance gives 121
- Opposite64, chance gives 60
The pairings astrologers name
| Couples whose Suns are | Counted | Chance |
|---|---|---|
| The same Sun sign | 69 · 9.5% | 60 · 8.3% |
| The same element | 192 · 26.4% | 180 · 24.8% |
| Signs said to get on | 365 · 50.2% | 364 · 50.0% |
| Opposite signs | 64 · 8.8% | 60 · 8.3% |
Same-sign couples come out a little ahead, 69 where chance gives 60. Random pairings reach that many 15 times in a hundred: a lean at most, not a rule.
The busiest pairings
Gemini and Scorpio lead with 16 couples. Deal the same people at random and the busiest pairing gets about 19 anyway, so none stands out.
How it was counted
762 famous couples with a page on this site, from Wikidata’s spouse and partner records. Each Sun sign is measured from NASA JPL’s ephemeris for the date of birth; the 35 couples where either Sun changed sign that day are left out rather than guessed.
Chance is the same people with partners dealt at random two thousand times, so a sign common among the famous is common in the baseline too.
Still together and split come from the same records’ dates: 155 couples with a start and no end, 471 with an end, each group set against its own people dealt at random. Couples with no dates, and those parted by a death, are in neither.

Two charts, not two signs
A Sun sign is one planet of ten. How two people talk, love and live together shows in every way their charts meet.
