What Is Synastry and How to Read It
Synastry compares two birth charts to reveal relationship chemistry, friction points, and long-term patterns beyond Sun-sign matching.

Synastry vs Sun-Sign Matching
Sun-sign compatibility is a starting point, not the full story. Synastry overlays two complete charts and tracks how each person's planets aspect the other's.
You may see strong chemistry through Venus-Mars links, emotional depth through Moon contacts, and long-term glue through Saturn or Jupiter aspects.
Key Planets to Compare
Moon-Moon contacts show emotional rhythm. Venus and Mars describe attraction and desire. Mercury aspects reveal communication under stress.
Saturn can indicate commitment and responsibility — or restriction if unmanaged. Jupiter often expands goodwill and shared growth.
How to Use Synastry Wisely
Difficult aspects are not breakup sentences. They show where awareness and skill-building matter most.
Combine synastry with communication, values, and life context. Astrology clarifies patterns; it does not replace choice.
