Frequently asked questions
What is synastry?
Synastry compares two birth charts to read relationship compatibility, by measuring the aspects between one person's planets and the other's.
Which synastry aspects matter most?
Sun–Moon, Venus–Mars, and Moon–Venus contacts are often read for attraction and ease; Saturn contacts can describe durability, responsibility, or pressure.
Are challenging synastry aspects bad?
No — squares and oppositions add friction that often creates chemistry and growth. Compatibility depends on the whole pattern.
