Maria Cunitz, Polish astronomer and author (born 1610)
Maria Cunitz
Maria Cunitz or Maria Cunitia was an accomplished Silesian astronomer, and the most notable female astronomer of the early modern era. She authored a book Urania propitia, in which she provided new tables, new ephemera, and a simpler working solution to Kepler's second law for determining the position of a planet on its elliptical path. The Cunitz crater on Venus is named after her. The minor planet 12624 Mariacunitia is named in her honour.
