What Is Synastry? The Astrology of Relationships
In astrology, synastry is the art of comparing two people’s birth charts to explore their relationship dynamics. 🌌✨
It’s a cosmic dance — revealing how your planets and theirs interact, where you harmonize, and where you challenge each other.
How Does Synastry Work?
Synastry overlays one person’s chart on another’s, looking at: ✅ Planet-to-planet aspects (e.g., your Moon square their Venus) ✅ How one person’s planets fall into the other’s houses
- Points of resonance or friction between the charts
Astrologers use synastry to explore romantic relationships, friendships, family ties, even business partnerships.
✨ “It’s not about perfect compatibility; it’s about understanding the cosmic chemistry between two souls.”

Synastry can help you understand: Where you naturally align Where you challenge or provoke each other How to navigate differences with awareness
It’s not about “good” or “bad” matches — even challenging aspects can create powerful growth when navigated consciously.
Beyond Synastry: Composite Charts
While synastry compares two individual charts, a composite chart blends them into a single symbolic chart — showing the essence of the relationship itself.

“Relationships are the mirrors in which we see ourselves most clearly.”
