Christiaan Huygens (1629-1695) discovered Saturn's satellite Titan. He was also the first to clearly see the planet's rings and to explain their appearance over time. Huygens made other significant contributions to astronomy as well. The Huygens probe, carried to Titan by Cassini, is named in his honor.
