He was the youngest of five children of Jacques Dominique, Comte de Cassini, who had succeeded his father as the director of the Paris Observatory, famous for completing the map of France. Jean-Dominique comte de Cassini ( June 30, 1748 - October 18, 1845) was a French Astronomer, son of César-François The Paris Observatory (in French Observatoire de Paris or Observatoire de Paris-Meudon) is the foremost astronomical observatory of France, He was also the great-great-grandson of famous Italian-French astronomer, Giovanni Domenico Cassini, discoverer of Jupiter's Great Red Spot and the Cassini division in Saturn's rings. Historically Astronomy was more concerned with the classification and description of phenomena in the sky while Astrophysics attempted to explain these phenomena Giovanni Domenico Cassini ( June 8, 1625 &ndash September 14, 1712) was an Italian Mathematician, Astronomer Saturn has the most extensive Planetary ring system of any planet in the Solar System.

The genus Cassinia was named in his honour by the botanist Robert Brown . Cassinia is a large Genus of plants in the family Asteraceae, most or all of which are native to the Southern Hemisphere. Robert Brown FRS ( 21 December, 1773 &ndash 10 June, 1858) was a Scottish scientist who is acknowledged as the leading botanist

He named many flowering plants and new genera in the sunflower family (Asteraceae), many of them from North America. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group He published 65 papers and 11 reviews in the [Nouveau] Bulletin des Sciences par la Société Philomatique de Paris between 1812 and 1821. Association of persons who love sciences The term philomatic (in french philomatique) is no longer in use

In 1825, A. Cassini placed the North American taxa of Prenanthes in the new genus Nabalus, now considered a subgenus of Prenanthes (family Asteraceae, tribe Lactuceae).

In 1828 he named Dugaldia hoopesii for the Scottish naturalist Dugald Stewart (1753-1828).
