Sun-sign-only compatibility makes for fun reading and bad decisions. Real astrological compatibility looks at two whole charts side by side.
Synastry — chart on chart
Synastry compares planet-by-planet aspects between two charts. Sun-Moon, Venus-Mars and Ascendant connections matter most.
Composite — the relationship's own chart
The composite is a single chart for the couple — how the relationship behaves as a third entity.
What astrology cannot tell you
It does not tell you whether the person is kind, faithful or growing. Two great charts can produce a terrible relationship, and two challenging charts can produce a beautiful one.
