Synastry Compatibility Guide
Discover how planetary aspects between two birth charts reveal relationship dynamics, compatibility, and connection patterns.
What is Synastry?
Synastry is the astrological practice of comparing two birth charts to understand relationship dynamics. Unlike individual natal chart readings, synastry examines how planets in one person's chart interact with planets in another person's chart through aspects—the angular relationships between celestial bodies.
Planetary aspects reveal how two people's energies combine, clash, or harmonize. These interactions explain attraction patterns, communication styles, emotional needs, and long-term compatibility potential. Understanding synastry aspects helps couples navigate challenges, recognize strengths, and build stronger relationships.
Each aspect type—conjunction, sextile, square, trine, and opposition—creates distinct relationship dynamics. Explore the guides below to understand how these aspects shape your connections with others.
