Mercury in Libra

Mercury in Libra 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. Libra is a cardinal air sign.

Of the 6,194 well-known people in StarMap's dataset, 540 have Mercury in Libra for the whole of their birth date. Bill Gates, Sung Jae-gi and Beyoncé are among them. Their commonest Sun signs are Libra (259), Virgo (199) and Scorpio (64). 49 more were born on a day Mercury moved into or out of Libra and are left out, because the hour decides and StarMap has no birth time for them.

What Mercury in Libra means

Read for how you think, talk and learn. If this is your placement:

You think by weighing both sides, and you communicate diplomatically, often finding the version of an idea that will land well with whoever is listening. You can take so long to settle on an opinion that the moment for it passes. You will change your mind in the middle of a conversation because the other point had merit.

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.
