The Synastry and Composite Charts are two of the most important tools in relationship astrology.

In the Composite Chart, the Moon represents the emotional foundation of the relationship. It describes how the couple experiences, processes, and expresses feelings together. It also reveals what the relationship needs in order to feel safe, supported, and emotionally fulfilled.

The Composite Moon can also show where the couple experiences the strongest emotional reactions, sensitivities, and challenges.

To properly interpret the Composite Moon, we look at the Moon’s sign, house placement, and the aspects it forms with other Composite planets.

In this article, we will explore the meaning of Composite Moon aspects.
