What Is Composite Chart in Astrology?
Also known as: Relationship Chart
Quick Definition
A single chart created by finding the midpoints between two people's natal charts, representing the relationship itself as its own entity.
Composite Chart: In-Depth Explanation
While synastry compares two individual charts, a composite chart creates an entirely new chart for the relationship. It's calculated by finding the midpoint between each pair of planets (your Sun and their Sun, your Moon and their Moon, etc.). The resulting chart describes the nature, purpose, and dynamics of the relationship as a whole — not as two individuals, but as a third entity they create together. Astrologers use composite charts to understand a relationship's core identity, challenges, and potential.
