Synastry: The Foundation of Relationship Astrology

Synastry is an astrological term to describe the results of two charts being overlayed. The overlay reveals how the birth charts relate to each other, i.e. the aspects they produce. Synastry charts can reveal a great deal about the positive and challenging parts of our relationships with others.
