☉ Sun ⚺ Semisextile ☿ Mercury

30° · minor aspect · neutral · default orb ±2°

Sun semisextile Mercury traditionally places identity and vital force in a direct combination with communication, language, and analytical structuring. Adjacent-sign aspect (30°). Classical sources treat it as minor and somewhat dissonant due to lack of shared element or modality. This describes the documented significations of the two bodies in relation, cited per tradition — not a prediction about any individual.

Astronomical note. Sun and Mercury never separate by more than about 28° on the ecliptic, so only the closer aspects between them can occur.
