Once you have uncovered your birth chart, the next step is to delve into a synastry chart to explore zodiac compatibility. Astrologers determine astrological compatibility between couples by comparing their birth charts using synastry charts.

It may seem straightforward at first, but when you consider zodiac signs, elements, planets, houses, and aspects, you realize how intricate this ancient art is. Let’s dissect some synastry basics to help you navigate the world of natal chart compatibility.
Understanding Synastry Charts
During a synastry chart reading, astrologers overlay two or more charts to create a bi-wheel. The inner ring represents the first person’s birth chart, while the outer chart shows where those planets land in relation to the first person’s chart.
For instance, if you are a Cancer rising with a Cancer moon and your partner has a Cancer sun, you would observe that their sun in Cancer aligns with your moon in Cancer in your first house. This alignment is considered synastry gold!
Astrologers consider various factors when analyzing synastry and love compatibility between individuals.

Zodiac Signs and Elements. Having planets and placements in compatible elements can enhance understanding and harmony in a relationship. Different elemental compositions in birth charts can lead to unique dynamics between partners.
Aspects. The aspects in a synastry chart describe how two planets interact with each other. Various aspects indicate different types of connections and challenges in a relationship.
Planets. The placement of planets in a synastry chart plays a significant role in understanding the strengths and challenges in a partnership. Different planet combinations can influence the dynamics between individuals.

Zodiac sign compatibility forms the foundation for understanding how elements interact with each other in a relationship.
