Giovanni Domenico Cassini

Giovanni Domenico Cassini was a 17th-century astronomer and mathematician from Italy who made significant contributions to our understanding of the solar system. He is best known for discovering the division in Saturn's rings, called the Cassini Division, and for his work on the orbits of planets and moons. Cassini also mapped the shape of the Earth's core and helped develop improved telescopes. His observations advanced planetary science and helped establish foundational knowledge for astronomy, influencing subsequent research and exploration of our celestial neighborhood.
