from Wikipedia, the free encyclopedia

Margaretha Kirch (* around 1703 in Berlin ; † after 1744 ) was an astronomer who worked in Berlin .

Live and act

Margaretha was the daughter of Gottfried Kirch and Maria Margaretha Kirch , and the youngest sister of Christfried Kirch and Christine Kirch . Few details are known about her life. She was only seven years old when her father died and never married.

Like her sister Christine, she was taught astronomy at the age of 10 and both initially assisted her brother Christfried with his observations. Margaretha later made observations of the weather and the starry sky, which she recorded in a weather observation diary.

Already on January 3, 1744 discovered long before the meteorologists Augustin Grischow in Berlin the Great Comet C / 1743 X1 and led observations and measurements with a 2 foot - and a 6-foot telescope through, the results of which they daily until 25 February made entries in her watch book .

After the comet had passed the sun , Margaretha observed and drew a streaky splitting of the comet's tail on March 5 , which was only observed on the following four days by well-known astronomers such as Joseph-Nicolas Delisle and Gottfried Heinsius in Saint Petersburg , as well as Jean-Philippe de Chéseaux in Lausanne . In particular, her observation of March 7th is also recorded in an engraving .
