Overview
What Is Synastry?
Synastry is the astrological art of comparing two birth charts. By overlaying one person's planets onto another's chart, astrologers can see how the two individuals interact — where there's harmony, where there's tension, and where growth happens. Synastry focuses on the between — the energy that flows when two people come together.

How to Read Synastry
Start with the personal planets: Sun (identity), Moon (emotions), Venus (love), Mars (passion). Then move to social planets: Mercury (communication), Jupiter (expansion), Saturn (commitment). Look for conjunctions and oppositions first — they're the most impactful. Trines show ease, squares show growth areas. The houses where planets fall reveal which life areas are activated in the relationship.
