FACTS:

Satellites: 62 moons


  • Galileo was the first to observe Saturn with a telescope in 1610.

  • Saturn's rings remained unique in the known solar system until 1977 when very faint rings were discovered around Uranus and shortly thereafter around Jupiter and Neptune.

  • Saturn was first visited by Pioneer 11 in 1979 and later by Voyager 1 and Voyager 2. Currently, Cassini is in orbit around Saturn, while the Huygens probe landed on Saturn's largest moon, Titan.

  • Saturn's equatorial and polar diameters vary by almost 10 percent, 74,901 miles and 67,563 miles, respectively. This is the result of its rapid rotation and fluid state.
