The Complex Dance of Planetary Aspects in Synastry

When two charts overlay, the planets form aspects with each other—conjunctions, trines, squares, oppositions, and sextiles being the most significant. Each aspect tells a different story about how energies interact between two people.

Harmonious Aspects

Sun-Moon Conjunctions or Trines: When one person’s Sun harmoniously aspects another’s Moon, there’s often a sense of emotional understanding and complementarity. The Sun person feels “seen” by the Moon person, while the Moon person feels emotionally supported by the Sun person’s energy.

Venus-Venus Conjunctions or Trines: These aspects suggest shared aesthetic values, similar approaches to affection, and mutual appreciation. Couples with these aspects often enjoy the same activities and find it easy to express love in ways the other person appreciates.

Jupiter Aspects: When one person’s Jupiter aspects another’s personal planets, there’s often a sense of mutual growth, optimism, and expansion in the relationship. The Jupiter person tends to encourage the other’s development and brings opportunities for learning.

Term Description
Venus Placement Venus governs what we value, how we express affection, and what we find beautiful. Someone with Venus in Cancer seeks emotional security and nurturing in relationships, while Venus in Aquarius craves intellectual stimulation and freedom.
7th House Known as the house of partnerships, the sign on your 7th house cusp and any planets within it reveal what you seek in committed relationships.
Mars Placement Mars shows our approach to desire, passion, and how we assert ourselves. A person with Mars in Libra might approach conflict indirectly and prioritize harmony, while Mars in Aries is direct and can be impulsive in pursuing desires.
Venus-Mars Aspects The aspects between your own Venus and Mars indicate how well your feminine and masculine energies integrate internally, which affects how you relate to others.

Challenging Aspects

Mars-Saturn Hard Aspects: When one person’s Mars squares or opposes another’s Saturn, friction can arise between action and limitation. The Mars person may feel restricted or criticized by the Saturn person, while the Saturn person might find the Mars person impulsive or disruptive.

Venus-Pluto Squares or Oppositions: These aspects can create intense attraction but also power struggles and jealousy. The connection is magnetic but potentially consuming, with themes of possession and transformation.

Moon-Mercury Challenging Aspects: When communication styles don’t align with emotional needs, misunderstandings become frequent. The Mercury person might seem insensitive to the Moon person, while the Moon person might seem overly sensitive to the Mercury person.
