In Gemini, Mercury is the star lord of 0 nakshatras and the sub-lord of 3 slices. Anything placed in those degrees — a planet or a house cusp — delivers its results through Mercury.
| Role | Degrees in Gemini | Nakshatra | Width |
|---|---|---|---|
| Sub-lord | 0°00′00″ – 1°53′20″ | Mrigashira (Mars) | 1.89° · ≈8 min of Ascendant motion |
| Sub-lord | 12°33′20″ – 14°26′40″ | Ardra (Rahu) | 1.89° · ≈8 min of Ascendant motion |
| Sub-lord | 23°53′20″ – 25°46′40″ | Punarvasu (Jupiter) | 1.89° · ≈8 min of Ascendant motion |
Mercury rules no nakshatra inside Gemini, so it can only act here as a sub-lord (or as the sign-level dispositor).
The narrowest Mercury sub-lord slice in Gemini is 1.89° wide, about 8 minutes of Ascendant motion; the widest is 1.89° (≈8 min). The Ascendant moves roughly 1° per 4 minutes on average, so a few minutes of birth-time error can change the sub-lord.
