One contact, exact to two hundredths of a degree
Ben Affleck and Matt Damon compatibility
↓ Below: all 2 aspects named, with orbs
Verified by a birth certificate or official record: full chart shown, including houses and the rising sign.
Note on this rating: Birth certificate, via AstroTheme.
This page compares Sun, Mercury, Venus and Mars, the four placements a birth date alone can place. Moon, Ascendant and Midheaven are left out here by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.
Cross-aspects
Where the two charts actually touch
The overlap
Two charts, laid over each other
Ben Affleck and Matt Damon's Sun, Mercury, Venus, Mars and Moon are drawn here, along with the house ring and ascendant axis both charts support. This is a complete chart of what is known, not a partial chart of what is not.

Why they click
Affleck's Sun squares Damon's Venus at an orb of 0.02 degrees. That is two hundredths of a degree from a perfect square, close enough to count as exact. A Sun meeting a Venus is one chart's identity landing on what the other finds worth having, and here it lands almost perfectly.
Why they clash
Both of the two contacts are squares, and there are only two. Affleck's Venus squares Damon's Mercury at 5.7 degrees alongside the near-exact one. Every category reads at the floor of 30, because five categories cannot be filled by two aspects. What the engine finds between these charts is a single point of extraordinary precision and almost nothing surrounding it.
What each system says
Twelve systems, two people
The Suns are 52.4° apart, outside orb of any aspect, which is why identity reads as an empty channel above.
Rat and Dog are in neither the trines nor the clashes.
Guna Milan: 17 of 36
A second tradition
Guna Milan (Ashtakoot)
Guna Milan is the compatibility method used in Vedic matchmaking, traditionally consulted before an arranged marriage. It scores eight factors between two Moon placements on a 36-point scale, shown here as what this one tradition reads: not a verdict, and not averaged with the Western reading above, which may disagree.
17 of 36 points
Two things stated plainly rather than left silent: Varna and Vashya use a directional rule from traditional bride/groom roles, applied here in the order the two people are listed on this page rather than assigning either role. Bhakoot dosha's most common cancellation, matching rashi lords, is applied; Nadi dosha carries no cancellation here, though same-nakshatra-different-pada is sometimes cited elsewhere as easing it. Mangal (Kuja) dosha is a separate check and isn't part of this reading.

See what a wider lens finds
This page compares Sun, Mercury, Venus and Mars, because those are the four that a birth date alone can place. With this few cross-aspects between the two, a midpoint chart is often the more informative object.
