Planetary Aspects: Conjunctions, Trines, Squares & More

Aspects are the conversations between planets in your birth chart. They reveal how different parts of your personality interact, conflict, or cooperate.

Understanding aspects transforms scattered planetary placements into a cohesive story. They show the dynamic relationships that create your unique psychological makeup.

What Are Planetary Aspects?

Aspects are specific angular relationships between planets in your birth chart. When planets are a certain number of degrees apart, they form geometric patterns that create energetic connections.

Think of aspects as:

  • Conjunction (0°) = Planets in the same room, blending energies
  • Trine (120°) = Planets in harmony, easy flow
  • Square (90°) = Planets in tension, conflict requiring action
  • Opposition (180°) = Planets across from each other, seeking balance
  • Sextile (60°) = Planets in opportunity, gentle support

Why Aspects Matter

Planets = what
Signs = how
Houses = where
Aspects = how they interact

Example:

  • Sun in Leo = Creative, confident self-expression
  • Moon in Scorpio = Deep, intense emotions
  • Sun square Moon = Internal conflict between pride and emotional vulnerability

The aspect reveals the relationship between your conscious identity (Sun) and emotional needs (Moon).

The Five Major Aspects

1. Conjunction (0°) — FUSION

Symbol: ☌
Orb: 8-10°
Nature: Neutral (depends on planets involved)

Meaning:
Two planets occupying the same space, blending their energies inseparably.

Interpretation:

  • Planets function as a unit
  • Energies reinforce each other
  • Can be harmonious or challenging depending on planetary compatibility

  • Venus ☌ Mars: Love and desire united, passionate nature, magnetic attraction
  • Moon ☌ Saturn: Emotions restricted, serious emotional nature, need for structure

Challenge: Can create one-dimensional expression if planets are too fused.

2. Trine (120°) — HARMONY
