Astrology doesn’t just reveal who you are — it can also help you understand your relationships. That’s where Synastry and Composite charts come into play. But what’s the difference?
🫂 Synastry: Cosmic Chemistry
Synastry overlays one person’s chart onto another’s to see how their planets interact. It’s like checking compatibility between two people’s energies.
- Venus-Mars contacts? Expect passion.
- Moon-Saturn links? Emotional security or emotional blocks.
- Mercury aspects? Communication highs or friction.
Synastry highlights attraction, friction, understanding, and potential challenges — but it doesn’t show the “third entity” that is the relationship itself.
💞 Composite: The Relationship’s Birth Chart
A composite chart is a completely new chart created by calculating midpoints between two charts. It reveals the identity and purpose of the relationship.
For example:
- A composite Moon in the 4th house may indicate a strong need to build a home together.
- Saturn in the 7th may suggest long-term potential but also karmic lessons.
💡 When to Use Each
- Synastry = How you affect each other.
- Composite = What your relationship becomes when you’re together.
Use both for a well-rounded view, especially in romantic or business partnerships.
