Saturn is the second-largest planet in the Solar System, and it’s the sixth planet from the Sun. Saturn is known for its spectacular rings, which are mostly composed of ice particles and rock dust. In 1997, NASA launched the Cassini–Huygens spacecraft to take pictures of Saturn and its sixty-two moons. Cassini’s images have led to many discoveries. However, the mission ended on September 15, 2017, as the space probe plunged toward Saturn, burning up as it passed through Saturn’s atmosphere.
