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
Justin Trudeau’s Mars and Katy Perry’s Neptune are 0.37 degrees from an exact square.
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.

21 of the 41 contacts fall between Sun and Pluto, and all 21 are in the grid. A boxed cell is within one degree. The other 20 contacts involve Chiron and the lunar nodes and are listed below, 1 of them in the tight layer.
A cell is a plain glyph. The aspect it names is a Codex Link in the sentences above.

Shared generation
5 of 41Jupiter through Pluto on both sides. Born 13 years 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
Sun sextile Sun at 1.28 degrees is the clearest contact, and identity scores highest of the five categories because of it. A sextile between two Suns describes people who find each other easy company without being especially alike, an angle of opportunity rather than fusion. Venus sextile Venus supports it with a compatible sense of taste. Where this pairing works, it works lightly and without much friction.
Why they clash
Venus square Sun at 1.13 degrees is the sharp note, and it cuts across the easy Sun contact: one person's affection meeting the other's identity at a hard angle. Mars quincunx Sun adds an adjustment on top. Communication, attraction, friction and values all sit at the floor, so almost nothing here is registering strongly in either direction. On this scale the chart describes a connection that is pleasant and shallow rather than difficult.
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 61.3° apart, close enough to feed the identity category 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
6 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 Justin Trudeau and Katy Perry astrologically compatible?
Their charts make 41 cross-aspects, the tightest at 0.37° and 0.88°. 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 square mean between two charts?
A square puts two placements at a right angle, generating friction that tends to force action. Justin Trudeau and Katy Perry have 10 square contacts between them, more than any other type.
