Understanding synastry — why compatibility goes deeper than sun signs

When people ask 'are we compatible?', they're often thinking about sun signs. But professional astrologers look at synastry — the comparison of two complete birth charts.

Synastry examines how each person's planets interact with the other's. A Venus-Mars conjunction might spark passion, while a Saturn square could signal challenges that require patience.

Aspects tell the story

Conjunctions, trines, and sextiles tend to flow easily. Squares and oppositions create tension that can be growth-oriented or challenging. Onne surfaces these patterns so you can navigate relationships with awareness.
