What is astrological synastry?
Synastry compares two birth charts to explore how your planets interact. It is not simply about whether you are compatible, but where attraction comes naturally, where the relationship needs conscious effort, and which themes keep returning between you. Matching sun signs only reveals the surface — the relationship between the Moon, Venus and the ascendant says far more about everyday life together, the way you handle conflict, and how safe you feel with each other.
