Moon-Moon Aspects: Emotional Compatibility in Relationships

Moon-Moon aspects in synastry are among the most important indicators of emotional compatibility. The Moon represents our emotional nature, needs, instincts, and how we feel secure. When two Moons form aspects between charts, they reveal how you understand each other emotionally, provide support, and create emotional safety together.

While Venus-Mars shows romantic and sexual chemistry, Moon-Moon aspects reveal the emotional foundation that sustains relationships long-term. Understanding these aspects helps you comprehend why some relationships feel naturally comfortable while others require constant emotional work, and how to better support each other's emotional needs.
