Mercury · Mutable air sign

Mercury in Gemini

Mercury in Gemini is where Mercury sat in the zodiac at the moment of birth, the part of a chart read for how you think, talk and learn. Mercury stays in a sign for two to ten weeks, longer when it turns retrograde. Gemini is a mutable air sign.

Of the 6,194 well-known people in StarMap's dataset, 417 have Mercury in Gemini for the whole of their birth date. Marilyn Monroe, Jean-Paul Sartre and Bob Dylan are among them. Their commonest Sun signs are Gemini (231), Cancer (96) and Taurus (83). 30 more were born on a day Mercury moved into or out of Gemini and are left out, because the hour decides and StarMap has no birth time for them.

Your mind moves fast across many subjects at once, and you communicate easily in almost any setting. The tension is skimming the surface of a topic and moving on before you have gone deep enough to be sure of it. The result is knowing a little about a great many things.

One placement is one part of a chart; the Sun, the Moon, the rising sign and the planets around them change how it plays out. Draw your whole chart to see the rest.

Positions are computed from each person’s birth date and place with the astronomy-engine ephemeris, checked against Swiss Ephemeris. Birth data comes from Wikidata; a placement is listed only when it holds for the whole birth date, and a rising sign only with a birth time Astro-Databank records. Readings describe tendencies, for entertainment and self-reflection; StarMap predicts nothing. Every planet in every sign.
