Compatibility & synastry

Real chemistry isn't whether two Sun signs match. It's how two whole charts fit together.

Astrological compatibility isn’t about whether two Sun signs ‘match’. It’s about how two whole charts fit together, a craft called synastry.

Synastry lays one person’s chart over another’s and reads the aspects between them: where your Venus meets their Mars, where your Moon soothes or snags on their Saturn. It shows where you flow, where you spark, and what quietly needs care.

Aspects work the same way between two people as within one chart. Drag to see the angles:

Now imagine one planet is yours and the other is theirs.

Beyond sun-sign matches

“A Leo and a Scorpio” is a fun shorthand, but real chemistry lives in the details: Moon to Moon for emotional safety, Venus to Mars for attraction, and the occasional hard aspect for the friction that keeps a bond alive.

Start with the aspects that drive it, and the signs each planet wears.

Common questions

What is synastry?

Synastry is the craft of comparing two birth charts by reading the aspects between them, to see where two people flow, spark and need care.

Is astrological compatibility just about Sun signs?

No. Sun-sign matching is a fun shorthand, but real chemistry lives in placements like Moon to Moon and Venus to Mars between two charts.

Which signs are most compatible?

There is no fixed list. Compatibility depends on the whole chart, not the Sun sign alone, so any two signs can work.
