Geometry
Exact angle: 0°. Lúmina working orb: 8°.
Interpretive function
Unites two planetary functions in the same region of zodiacal longitude; it is not automatically easy or difficult.
Why the planets matter
The aspect describes the relationship between functions; the planets tell us which functions are negotiating. A Venus–Saturn square is therefore not the same problem as a Mercury–Mars square.
Orb policy
Orb practice varies among astrologers. The numbers above are Lúmina v1 reproducibility standards rather than claims of universal agreement.
Concentration rather than agreement
Because the planets occupy nearly the same longitude, their functions become difficult to separate. That can create focus, mutual reinforcement or interference. A Mars–Saturn conjunction does not mean Mars and Saturn “agree”; it means assertion and constraint have to operate in the same place.
Applying and separating
An applying aspect is moving toward exactness; a separating aspect has already perfected. This distinction can change emphasis and timing, but it does not erase the aspect geometry or the condition of the planets involved.
Natal aspect versus transit
In transit work, a conjunction concentrates attention on the natal function being contacted. Repeated passes caused by retrograde motion can turn one contact into a longer developmental sequence.
Interpretation checklist
- Name both planetary functions.
- Check sign and house condition.
- Measure the actual orb.
- Distinguish natal pattern from temporary transit.
- Confirm the symbolism against observed context.
Three concrete examples
Sun–Mercury can concentrate identity and language; Venus–Mars can combine valuation and pursuit; Saturn–Moon can make emotional regulation negotiate directly with limit and duty. None of those contacts can be interpreted from “conjunction” alone.
What not to conclude
An aspect is not an event generator. It describes geometry between functions. A natal aspect cannot prove a diagnosis, relationship outcome or future incident, and a transit requires actual natal contact and context before a specific claim is justified.
