What Are Astrology Aspects?
In astrology, aspects are angular relationships between planets and other important points in a birth chart.
Astrologers traditionally interpret these angles as relationships between different planetary energies or symbolic themes.
Understanding aspects can help you read a birth chart beyond individual planets and zodiac signs.
Why Are Aspects Important?
A birth chart is not simply a collection of separate planetary positions.
Astrologers traditionally look at how planets relate to one another.
For example, Mercury represents communication and thinking, while Mars is associated with action and energy.
An aspect between Mercury and Mars may therefore be interpreted by astrologers as an interaction between communication and action.
Major Astrology Aspects
The five major aspects commonly discussed in Western astrology are:
- Conjunction
- Sextile
- Square
- Trine
- Opposition
Conjunction
A conjunction occurs when two planets are close together in the zodiac.
The commonly used angle is approximately 0 degrees.
Astrologers traditionally interpret a conjunction as combining or blending the symbolic meanings of the planets involved.
For example, a Venus-Mars conjunction might traditionally be interpreted as a strong interaction between relationship themes and desire or action.
Sextile
A sextile occurs when planets are approximately 60 degrees apart.
Astrologers traditionally associate sextiles with opportunities, cooperation, and supportive interactions.
Square
A square occurs when planets are approximately 90 degrees apart.
Squares are traditionally interpreted as creating tension, challenges, or friction between the planetary themes involved.
Trine
A trine occurs when planets are approximately 120 degrees apart.
Astrologers traditionally associate trines with ease, flow, and naturally supportive relationships between planetary themes.
Opposition
An opposition occurs when planets are approximately 180 degrees apart.
Astrologers traditionally interpret oppositions as relationships involving polarity, contrast, or the need to balance two different themes.
What Is an Orb?
An orb refers to the amount by which an aspect can differ from its exact angle while still being considered significant.
For example, if a square is exactly 90 degrees but two planets are 94 degrees apart, an astrologer may still consider the relationship a square depending on the chosen orb.
Different astrologers use different orb ranges.
Applying and Separating Aspects
Some astrology systems also distinguish between applying and separating aspects.
An applying aspect occurs when planets are moving toward an exact aspect.
A separating aspect occurs after the planets have passed the exact aspect.
This distinction is more commonly used in traditional astrology.
Aspects and Birth Charts
A birth chart can contain many aspects between planets.
For example:
- Sun trine Moon
- Venus square Mars
- Mercury sextile Jupiter
- Mars opposition Saturn
Astrologers traditionally interpret each combination according to the planets involved and the type of aspect.
Major vs Minor Aspects
The five aspects above are generally considered major aspects.
Some astrologers also use minor aspects, such as:
- Quincunx
- Semi-sextile
- Semi-square
- Sesquiquadrate
Different astrology traditions may use different sets of aspects.
Aspect Patterns
Sometimes several aspects form recognizable patterns in a birth chart.
Examples include:
- Grand Trine
- T-square
- Grand Cross
- Yod
These patterns can involve several planets and are interpreted as combinations rather than isolated aspects.
Final Thoughts
Astrology aspects provide a way of interpreting relationships between planets in a birth chart.
A useful way to understand an aspect is to consider:
Planet A + Aspect + Planet B
The resulting interpretation is then considered alongside the zodiac signs, houses, and the rest of the chart.
