Mercury in Leo

Mercury in Leo 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. Leo is a fixed fire sign.

Of the 6,194 well-known people in StarMap's dataset, 450 have Mercury in Leo for the whole of their birth date. Michael Jackson, Nelson Mandela and George W. Bush are among them. Their commonest Sun signs are Leo (221), Cancer (145) and Virgo (70). 37 more were born on a day Mercury moved into or out of Leo and are left out, because the hour decides and StarMap has no birth time for them.

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.
