🔍 What Is Synastry?
Synastry is the practice of comparing two individuals’ birth charts to interpret the potential dynamics in their relationship. Instead of predicting the future, synastry provides insight into how energies blend—or clash—between two people. It focuses on key planets that influence personal traits and relationships:
- Sun: Core identity, ego, vitality
- Moon: Emotions, instincts, subconscious
- Venus: Love, beauty, romantic attraction
- Mars: Passion, sex drive, physical energy
By analyzing these planetary signs from both individuals, astrologers can determine how compatible a couple might be on an emotional, romantic, and energetic level.

💞 Why Synastry Aspects Matter in Relationships
Each aspect between planets carries unique energy:
| Aspect | Degree | Meaning |
|---|---|---|
| Conjunction | 0° | Powerful unity or amplification |
| Sextile | 60° | Smooth flow, cooperation |
| Trine | 120° | Natural affinity, ease |
| Square | 90° | Conflict, tension, growth |
| Opposition | 180° | Complementary yet polarizing |
| Quincunx | 150° | Need for adjustment |

Understanding these aspects in the context of Sun, Moon, Venus, and Mars signs helps partners:

- Improve communication
- Balance contrasting needs
- Enhance intimacy and cooperation
- Recognize challenges early in the relationship
📈 Interpreting Compatibility Scores
Your overall score is based on a weighted system that emphasizes the emotional (Moon), romantic (Venus), and physical (Mars) dynamics more than just the Sun signs. Here’s a breakdown:

- 60–79%: Good – Minor friction, mostly harmonious
- 40–59%: Average – Mixed results; requires conscious effort
- Below 40%: Challenging – Contrasting energies; more growth needed
