This page compares the nine bodies a birth date alone can place, Sun through Pluto, and lists the Chiron and lunar node contacts alongside them. The Moon is drawn as the span it could have moved through and is scored in nothing here; the ascendant axis and the house ring are left out by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.
The overlap
Where the two charts touch
Venus Williams’s Chiron and Serena Williams’s Venus are 0.03 degrees from an exact opposition.
Both birth times are exact, so the Moon joins Sun through Pluto on both axes, and every contact also carries the house it falls in on the other person’s chart. The ascendant axis and the house ring are drawn.

24 of the 39 contacts fall between Sun and Pluto, and all 24 are in the grid. A boxed cell is within one degree. The other 15 contacts involve Chiron and the lunar nodes and are listed below, 6 of them in the tight layer.
A cell is a plain glyph. The aspect it names is a Codex Link in the sentences above.
Venus Williams inner ring, Serena Williams outer ring, with the contacts inside one degree drawn. 3 of them are between Sun and Pluto; the rest involve bodies that are not on either ring.

Trines and sextiles are soft, squares, oppositions and quincunxes hard. A conjunction depends on which two bodies meet, so it carries no tone here.
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
This is what comparing two charts system by system looks like: the same birth data on both sides, read against each other one system at a time.
The Suns are 97° apart, outside orb of any aspect, which is why identity reads as an empty channel above.
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.
The reading
26.5 of 36
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?
Their charts make 39 cross-aspects, the tightest at 0.03° and 0.19°. 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.
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 9 trine contacts between them, more than any other type.
