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
Freddie Mercury’s Pluto and Brian May’s Pluto are 0.12 degrees from an exact conjunction.
Neither birth time here is exact, so the Moon is not scored against anything and the ascendant axis and house ring are not drawn. Sun through Pluto move at most about two degrees in a day, so every contact below is the same whatever the time. This is the whole of what a birth date can place, not a sample of it.

19 of the 32 contacts fall between Sun and Pluto, and all 19 are in the grid. A boxed cell is within one degree. The other 13 contacts involve Chiron and the lunar nodes and are listed below, 2 of them in the tight layer.
A cell is a plain glyph. The aspect it names is a Codex Link in the sentences above.
Freddie Mercury inner ring, Brian May outer ring, with the contacts inside one degree drawn. 5 of them are between Sun and Pluto; the rest involve bodies that are not on either ring.

Within one degree
7 of 32The contacts closest to exact, whichever bodies they involve. 2 of these are Chiron or lunar node contacts, so they are named here and are not in the grid above. Tightest first, which is the only order that holds for every pair.

Shared generation
6 of 32Jupiter through Pluto on both sides. Born 10 months apart, these two have their outer planets in nearly the same degrees, so anyone born near them shares most of this group. Listed because it is real, kept apart because it says little about the pair.

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
Attraction reads 75, well clear of every other category here. Sun sextiles Venus at 1.32 degrees and Mars trines Mars at 4.2, so the pull and the working tempo both have somewhere easy to go. In a synastry built mostly from hard angles, those two contacts carry the whole supportive side.
Why they clash
Four of the six contacts are squares, and they are tight ones: Sun to Mars at 0.86 degrees, Mars to Mercury at 1.7, Venus to Sun at 2.25, Mars to Venus at 3.73. Both charts' Mars sits under pressure from the other side. High attraction stacked on four squares describes a pairing that generates heat by not agreeing.
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 46.3° 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.

Frequently asked
Are Freddie Mercury and Brian May astrologically compatible?
Their charts make 32 cross-aspects, the tightest at 0.12° and 0.17°. 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 Freddie Mercury and Brian May 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 square mean between two charts?
A square puts two placements at a right angle, generating friction that tends to force action. Freddie Mercury and Brian May have 11 square contacts between them, more than any other type.
