Frequently Asked Questions

What is a synastry chart?

A synastry chart is an astrological tool that overlays two people's natal charts to analyze how their planets interact. It reveals areas of harmony, attraction, tension, and growth potential in any relationship — romantic, friendship, or professional.

What are the best synastry aspects for love?

The strongest love indicators include Venus conjunct Mars (magnetic attraction), Sun conjunct Moon (deep emotional bond), Venus trine Venus (shared values), and Moon conjunct Descendant (instinctive partnership). Jupiter aspects bring generosity and growth, while Pluto aspects add intensity and transformation.

How do I read my synastry chart?

Look at how one person's planets aspect the other's. Conjunctions (0°) and trines (120°) indicate ease and flow. Squares (90°) and oppositions (180°) show tension but also passion. Pay special attention to Venus, Mars, Moon, and Sun contacts, as these govern attraction and emotional bonding. Our AI interprets all of this automatically.

What is the difference between synastry and composite charts?

Synastry compares two separate charts side by side to see how two individuals interact. A composite chart creates one single chart by calculating the midpoints of both people's planets — it represents the relationship itself as its own entity. Both methods offer valuable but different insights into a partnership.
