Relationship astrology is a branch of astrology that studies the interactions between two birth charts. Unlike traditional horoscopes, it doesn't just analyze one individual: it illuminates the dynamics that emerge when two people meet.

What is Synastry?

Synastry is the main technique of relationship astrology. It involves overlaying two birth charts to observe how the planets of one interact with those of the other. A Sun in conjunction with the Moon, for example, often creates strong attraction and deep emotional understanding.

Key Aspects to Analyze

Among the most revealing aspects:

  • Sun/Moon: emotional complementarity
  • Venus/Mars: physical and romantic attraction
  • Saturn: stability and long-term commitment
  • Mercury: communicational compatibility
