Synastry is a highly sophisticated art that involves the comparison of two natal charts to determine areas of strength and weakness in a relationship. Synastry is a valuable tool for people who want to examine their relationship with another person based on the interplay of aspects between the two birth charts.
Basic Synastry Chart Interpretation
Before you can understand the basics of a synastry chart, you'll need the be able to recognize the astrological glyphs (symbols) and have an understanding of the astrological signs, planets, aspects, and houses. You'll also need to have a grasp of the basics of interpreting a natal chart because many issues in the individual natal charts can mitigate or intensify the aspects found in the couples synastry.
What a Synastry Chart Looks Like
A synastry chart is a bi-wheel chart that looks almost like a birth chart, except there are two charts, one chart is placed around the outside of the other. The synastry chart below is that of Katy Perry and Orlando Bloom, who became engaged on February 14, 2019. Katy's chart is in the middle; her placements are in blue. Orlando's chart is on the outside; his placements are in red.
The Aspects in Synastry
Popular Sun Sign compatibility considers how one astrological sign relates another. Synastry is more complex, nuanced, and exact. It deals with how the degree of the signs a planet or other important placements occupy in one chart aspect the degrees of the planets and other important placements by sign occupy the second chart. Keep in mind that just because planets are in the same sign, or in signs that sextile, square, trine or oppose one another, the planets aren't in aspect unless they are within the orb of influence.
Orb of Influence
The "orb" of influence refers to the exactness of an aspect. If orb is tight (almost exact), the aspect is more powerful. In synastry, an orb of 4° or less will reveal the essential features of the relationship. Those with greater orbs fill in the background of the relationship.

However, because Orlando also has a Scorpio Moon square Saturn natally, the often emotionally depressing connection has been mitigated. Orlando, rather than weighing Katy done emotionally, is more likely to stabilize Katy's intense and anxious emotional nature and provide her with a feeling of security.

Mars square Pluto is considered one of the most challenging aspects in synastry. It speaks of explosive tempers, burning desires, and the need to prove something. Katy's Mars at 14°24 Capricorn is square (0°13' from exact) Orlando's Pluto at 14°11' Libra. This square describes a mutually exciting exchange of energy that's fueled by an emotional intensity that can provoke turbulence in Katy and Orlando's relationship. This aspect can spark passionate sex as well as passionate fights. However, if Katy and Orlando are truthful and honest with each other and work as a team, theirs can be a power coupling.
In synastry, the interplay of houses between two charts determines what area of life will be affected concerning the planets involved. In the synastry between Katy and Orlando:
- Orlando's Sun shines in Katy's third house, which indicates that he mentally stimulates Katy and she feels smarter when she's around him.
- Katy's Sun shines in Orlando's eighth house. This placement indicates a relationship in which Orlando feels a strong emotional bond that could frighten and bewitch him at the same time.
What Synastry Can and Can't Do
Great synastry doesn't always translate into a perfect relationship. Many variables exist when two people come together. Each individual carries the baggage of their past experiences, family history, social background, and much more into the relationship, and this can result in an endless number of outcomes. However, what synastry can do is give you a different perspective and tell you where there can be ease or difficulties in a relationship. The future of any relationship does not depend upon good synastry, it's always determined by the individuals.
