Saturn : the planet sixth in order from the sun — Webster   See also   OneLook


Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn’s interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. The planet’s most notable feature is its prominent ring system, which is composed mainly of ice particles, with a smaller amount of rocky debris and dust. — Wikipedia

Visit Saturn This 360° video voyage to Saturn will leave you feeling like you have actually just took a space trip to the incredible ringed planet. You will fly passed its moons Rhea, Tethys, Iapetus and get up close to Enceladus to see its mysterious but beautiful tiger stripes. You will then sling shot around Titan and then on to Saturn its self, were you will glide around its beautiful rings. — VR 360 TV

Cassini–Huygens Mission was a collaboration among NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites. The Flagship-class robotic spacecraft comprised both NASA’s Cassini space probe and ESA’s Huygens lander, which landed on Saturn’s largest moon, Titan. Cassini was launched on October 15, 1997, and it entered Saturn’s orbit on July 1, 2004. The mission ended on September 15, 2017, when Cassini’s trajectory took it into Saturn’s upper atmosphere and it burned up. — Wikipedia

Pioneer programs were two series of United States lunar and planetary space probes exploration. The first program, which ran from 1958 to 1960, unsuccessfully attempted to send spacecraft to orbit the Moon, successfully sent one spacecraft to fly by the Moon, and successfully sent one spacecraft to investigate interplanetary space between the orbits of Earth and Venus. The second program, which ran from 1965 to 1992, sent four spacecraft to measure interplanetary space weather, two to explore Jupiter and Saturn, and two to explore Venus. The two outer planet probes, Pioneer 10 and Pioneer 11, became the first of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System. — Wikipedia

Voyager Program is an American scientific program that employs two robotic interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable alignment of Jupiter and Saturn, to fly near them while collecting data for transmission back to Earth. — Wikipedia
