Cassini, Gian Domenico

Cassini, Gian Domenico
(8 jun. 1625, Perinaldo, República de Génova–14 sep. 1712, París, Francia).

Astrónomo francés de origen italiano. Sus primeros estudios fueron principalmente observaciones del Sol. Sin embargo, después de obtener telescopios más potentes, volvió su atención a los planetas. Calculó los períodos de rotación de Júpiter y Marte y compiló una tabla con las posiciones de los satélites de Júpiter. Sus observaciones de la Luna (1671–79) le permitieron compilar un gran mapa. En 1683, después de estudiar la luz zodiacal, concluyó que esta era de origen cósmico. Descubrió cuatro de las lunas de Saturno: Japeto (1671), Rea (1672), Tetis (1684) y Dione (1684). La zona oscura entre dos de los anillos principales de Saturno (la división Cassini) fue bautizada en su honor.
