Synastry compares two charts side by side. A composite chart goes deeper — it takes the midpoint between every planet in both charts and builds a single new chart. Not "you and them" — the relationship as its own being, with its own Sun, Moon, and Ascendant.
Two birth charts overlaid. Shows how your planets touch theirs — chemistry, friction, attraction. The conversation between two people.
One chart, built from the midpoints. The relationship as a third entity — its own personality, purpose, and timing.
Composite charts are what professional astrologers reach for when the question shifts from "do we click?" to "what is this relationship actually here to do?"
The three luminaries below are the core of the relationship — its identity, its inner life, and how it shows up in the world.
Every placement below is the midpoint of the two natal positions, computed with Swiss Ephemeris. These are the personal blueprint of the relationship itself.

The composite chart is the bones. Our Compatibility Deep Dive is the full reading — a custom PDF that interprets every cross-aspect, every composite placement, and what this relationship is actually here to teach you both.

Composite Sun tells you the central purpose of the relationship — the thing it keeps coming back to.
Composite Moon is its emotional climate — how it feels when you're together day to day.
Composite Ascendant is the face it shows the world — how others perceive you as a unit.
A composite chart isn't a verdict. It's a blueprint — the moment to know what you're building together.
