The Composite Chart: Your Relationship's Blueprint
Synastry shows how two people interact. The composite chart shows the relationship itself as a living entity with its own chart, personality, and destiny.
What Is a Composite Chart?
Created by finding the midpoint between each pair of corresponding planets in two natal charts. Your Sun at 10 Aries and your partner's Sun at 20 Leo? The composite Sun is at 0 Gemini. Do this for every planet and you have a chart representing not either person, but the relationship they create together.
Key Placements
### Composite Sun
The core purpose of the relationship. Sun in the 1st house: strongly identified as a unit. Sun in the 4th: centered on home and family. Sun in the 10th: the couple builds something together publicly.
### Composite Moon
The emotional atmosphere. Moon in Cancer: deep nurturing. Moon in Aquarius: emotional independence. Moon in Scorpio: intense bond demanding vulnerability.
### Composite Venus and Mars
Venus shows how the couple expresses love. Mars shows how they handle conflict and desire. Venus in the 5th: playful and romantic. Mars in the 12th: hidden conflicts or suppressed anger.

### Composite Saturn
The commitment indicator. Strong Saturn means staying power and willingness to work through difficulty. Challenged Saturn means the relationship feels heavy or obligatory. No Saturn aspects can mean pleasant but lacking gravity.
Composite vs. Synastry
Synastry shows the chemistry between two people. The composite shows the substance of what they create together. A relationship can have exciting synastry but a difficult composite: passionate interactions that never coalesce into stable partnership. A strong composite with muted synastry: a relationship that works beautifully even if initial chemistry was subtle.
The Deeper Teaching
A relationship is not just two people standing next to each other. It is a new creation with its own life and needs. The composite chart suggests this is literally true. You can explore composite charts on Celesian by entering both birth details.
