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
Venus Williams and Serena Williams'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.
| Thin line, Mars to Venus | SEXTILE 1.61° |
| Thin line, Sun to Mercury | TRINE 2.86° |

Why they click
Mars sextiles Venus at 1.61 degrees, Sun trines Mercury at 2.86, and Mercury trines Venus at 4.63. Attraction reads highest of the five categories at 44. Every contact these charts make is a supportive one, describing a pairing that runs warm and unforced.
Why they clash
There is no square, opposition, or conjunction anywhere in this synastry. Four of the five categories sit at the floor of 30. Charts that never meet at a hard angle also never generate the pressure that forces a matter to a decision, so what looks frictionless from outside is mostly an absence of contact.
What each system says
Twelve systems, two people
The Suns are 97° apart, outside orb of any aspect, which is why identity reads as an empty channel above.
Monkey and Rooster are in neither the trines nor the clashes.
Guna Milan: 26.5 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.
26.5 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.

Frequently asked
Are Venus Williams and Serena Williams astrologically compatible?

What does trine mean between two charts?
A trine puts two placements in easy relation, a flow that takes little effort to access. Venus Williams and Serena Williams have 2 trine contacts between them, more than any other type.
Exact, and all soft
Read the relationship as one chart
This page compares Sun, Mercury, Venus and Mars, because those are the four that a birth date alone can place. With no hard contact between the two, a composite chart, the midpoint of both, often reads clean.
