Note on this rating: Birth date 1972-04-17 from Wikidata Q172044 (day precision) and the English Wikipedia article. Birth city Houston, Texas from Wikidata P19. Birth time unknown, so Rodden X and the time is an estimate.
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.

The overlap
Two charts, laid over each other
Ben Affleck and Jennifer Garner's Sun, Mercury, Venus and Mars are drawn here, the four placements a birth date alone can place with no birth time required. This is a complete chart of what is known, not a partial chart of what is not.
| Thin line, Mercury to Venus | SEXTILE 2.12° |
| Thin line, Mars to Sun | TRINE 2.66° |
| House ring, not drawn | |
Why they click
Four of the five aspects here are soft. Sun trine Sun, Mars trine Sun at 2.66, and two Mercury sextiles reaching Venus and Mars. That combination describes two people who get along without effort: compatible identities, compatible pace, and an easy channel between thinking and both affection and drive.
Why they clash
Venus square Mercury at 3.3 degrees is the lone hard angle, placing affection against the other's way of thinking. Every category sits at or just below the floor, including identity, which lands slightly under it. Soft aspects alone do not lift a score on this scale, because ease is not the same as intensity. This chart reads as comfortable and low-voltage rather than as difficult.
What each system says
Twelve systems, two people
The Suns are 115.1° apart, close enough to feed the identity category above.
Rat and Rat are in neither the trines nor the clashes.

Frequently asked
Are Ben Affleck and Jennifer Garner astrologically compatible?
Their charts make 5 cross-aspects, the tightest at 2.12° and 2.66°. Astrology does not score a relationship out of a hundred, and the number on this page counts how much contact two charts make, not how well two people do.
Why isn't there a house ring on the chart above?
At least one of Ben Affleck and Jennifer Garner doesn't have a curated, non-estimated birth time, so a house placement would be a guess. This page only shows what a birth date alone can place.
What does trine mean between two charts?
A trine puts two placements in easy relation, a flow that takes little effort to access. Ben Affleck and Jennifer Garner have 2 trine contacts between them, more than any other type.
