The Composite Chart is one of the most important tools in relationship astrology because it reveals the energy created when two people come together. While the individual birth charts describe each person, the Composite Chart describes the relationship itself.
The Sun represents the heart, identity, and purpose of the relationship. By examining the Composite Sun’s aspects to other planets, we can gain insight into the couple’s strengths, challenges, emotional connection, communication style, attraction, and long-term potential.
In this article, we explore Composite Sun aspects, including the conjunction, sextile, trine, square, and opposition to each planet, and what they reveal about the unique dynamic between two people.
