Synastry — Partner Compatibility by Natal Charts

Synastry reveals how two natal charts interact. It is one of the key tools in relationship astrology, helping to understand the emotional, psychological, and life compatibility of two people.

The synastry page on DestinyKey lets you calculate partner compatibility online, view two individual charts, a combined bi-wheel, cross-chart aspects, and the placement of one person's planets in the other's houses.

What matters in synastry?

The most significant factors are aspects between personal planets — Moon, Venus, Mars, and Sun — as well as the placement of a partner's planets in key houses of your chart. This reveals the strength of attraction, emotional closeness, conflict zones, and partnership potential.

What can synastry tell you?

Synastry helps you understand how easy it is for two people to be together, where they strengthen each other, where contradictions may arise, how romantic, emotional, and psychological bonds are formed, and what challenges the relationship faces.

Astropsychological Compatibility Analysis

DestinyKey enhances the synastry calculation with a quick astropsychological compatibility analysis. In 1–2 minutes the user receives a clear interpretation of the couple's strengths, risks, communication style, and relationship potential. This goes beyond a simple aspect table to paint a living picture of how two people interact.
