What Synastry Reveals
Synastry is the technique of overlaying two birth charts to assess relationship compatibility. When Person A's planets land in Person B's chart houses and form aspects to Person B's planets, the interaction reveals the relationship's nature attraction, tension, growth areas, and potential breaking points. Synastry does not predict whether a relationship will succeed. It maps the energetic dynamics between two people, showing where friction arises and where genuine chemistry lives.
Key Synastry Aspects to Check
- Sun-Moon conjunction or trine fundamental compatibility, mutual understanding
- Venus-Mars aspects physical attraction and desire
- Moon-Moon harmony emotional ease and domestic compatibility
- Saturn contacts commitment, longevity, but also restriction
- Ascendant contacts powerful first impressions and identity recognition
- 7th house overlays one person's planets in the other's 7th signal partnership potential
Reading Synastry Step by Step
Generate both charts with exact birth times. First check house overlays where do Person A's planets fall in Person B's house system? Those houses light up in B's life through A. Then list all inter-aspects, focusing on conjunctions, squares, trines, and oppositions. Challenging aspects (squares, oppositions) create dynamic tension not deal-breakers, but areas needing awareness. The best relationships show a mix of supportive trines and challenging aspects that generate growth.
