Correct Answer: Christiaan Huygens
Solution : The correct answer is Christiaan Huygens.
The first person to correctly characterise Saturn's rings as a disc encircling the planet was the Dutch scientist Christiaan Huygens in 1655. Huygens finds Titan, the first moon of Saturn, seven months before the ring plane crosses that year, using a 50-power refractor that he made himself. The mysteries surrounding the ring system have only grown larger since NASA's Voyager 1 and 2 probes conducted extensive observations in 1980 and 1981.
