Frequently Asked Questions
What is synastry? ›
A comparison of two birth charts: the aspects one person’s planets make to the other’s planets and points describe the dynamics between them.
How is the synastry score calculated? ›
Seven relationship dimensions are scored from the aspect matrix and calibrated against a reference sample of real couples. Each aspect type and planet pair uses its own orb tolerance.
Does a low score mean the relationship won’t work? ›
No. The score measures how easily energy flows between the charts; it cannot measure effort, communication or timing. Hard aspects often mark the areas where a relationship grows.
What is the difference between synastry and a composite? ›
Synastry is two separate charts facing each other; a composite is a single "relationship chart" derived from both. Read together, they complete the picture.
