    ✦ Report Coverage

    Eight Synastry Dimensions

    Every dimension in your report covers how your charts interact — not generic horoscope predictions.

    Venus–Mars Aspects

    The attraction axis. How Venus (love, receptivity) and Mars (desire, initiative) interact between two charts determines the spark and physical drawing.

    Sun–Moon Aspects

    The emotional resonance axis. Sun–Moon conjunctions and trines create a deep sense of recognition — 'I feel at home with you.'

    Rising Sign Overlay

    How does each person see the other? The Ascendant overlay reveals first impressions, physical attraction, and the public face of the relationship.

    Mercury Aspects

    Communication compatibility. Do you understand each other easily, or is there friction in how you think and express yourselves?

    Saturn Contacts

    Long-term glue. Saturn aspects indicate karmic ties, responsibility, and whether this feels serious and lasting — or restricting.

    Moon–Moon & Moon–Venus

    Emotional compatibility. How your emotional natures meet, and whether you nurture each other's inner worlds.

    7th House Activations

    Which of your planets land in the other person's 7th house (the house of partnership)? These create profound relationship pull.

    North Node Contacts

    Karmic destiny connections. North Node aspects in synastry indicate a relationship that feels fated and pushes both people toward growth.

    ✦ How It Works

    What Is Western Synastry?

    Synastry is the branch of Western astrology that compares two birth charts to understand how two people interact. Your planets are overlaid on the other person's chart — and vice versa. The aspects formed between planets tell a story about attraction, tension, communication, emotional resonance, and long-term potential.

    When your Venus conjuncts someone's Mars, there is almost certainly a magnetic physical attraction. When your Saturn squares their Sun, there may be a feeling of pressure. When your Moon trines their Moon, emotional understanding flows naturally. Synastry describes the dynamics both people are working with — understanding them helps you navigate consciously.

    Attraction

    Venus, Mars, and Ascendant contacts show the spark and physical draw.

    Emotional Bond

    Moon contacts and 4th house overlays show emotional safety and depth.

    Long-term Fit

    Saturn and North Node aspects show karmic weight and lasting potential.
