What is a Composite Chart?

Imagine overlaying two birth charts over one another then finding both their individual suns, and placing a new sun in between them - that is essentially how composite charts are determined. In more formal terms, composite charts are determined by calculating the midpoint between both people's planetary positions and creating an entirely new chart with the new planetary position and aspect.

Composite charts and synastry charts are similar in that they both explore relationships. However, composite charts differs in that it creates an entirely new chart out of two individual’s charts. A composite chart is looking at the two individuals as a unit - as a whole. Thus why, visually it looks exactly like a birth chart as it only has one set of elements.
