Voyager 2 found that at the highest levels (7 kilopascals pressure) Saturn's temperature was 70 K (−203 °C) (i.e. 70 degrees above absolute zero), while at the deepest levels measured (120 kilopascals) the temperature increased to 143 K (−130 °C). The north pole was found to be 10 K cooler, although this may be seasonal. Unfortunately ...
The first human being to reach space (defined as an altitude of over 100 km) and to orbit Earth was Yuri Gagarin, a Soviet cosmonaut who was launched in Vostok 1 on April 12, 1961. The first human to walk on the surface of another Solar System body was Neil Armstrong , who stepped onto the Moon on July 21, 1969 during the Apollo 11 mission ...
Pioneer 11 passed by Saturn on September 1, 1979, at a distance of 21,000 km (13,000 mi) from Saturn's cloud tops. [ 27 ] By this time, Voyager 1 and Voyager 2 had already passed Jupiter and were en route to Saturn, so it was decided Pioneer 11 would pass through the Saturn ring plane at the same position Voyager 2 would later have to fly ...
1979 – Pioneer 11 flies by Saturn, providing the first ever closeup images of the planet and its rings. It discovers the planet's F ring and determines that its moon Titan has a thick atmosphere. [199] 1979 – Goldreich and Tremaine postulate that Saturn's F ring is maintained by shepherd moons, a prediction that would be confirmed by ...
Saturn takes about 10.7 hours (no one knows precisely) to rotate once on its axis—a Saturn “day”—and 29 Earth years to orbit the sun. Saturn is a gas giant and does not have a solid ...
Saturn is named after the Roman god of wealth and agriculture, who was the father of the god Jupiter.Its astronomical symbol has been traced back to the Greek Oxyrhynchus Papyri, where it can be seen to be a Greek kappa-rho ligature with a horizontal stroke, as an abbreviation for Κρονος (), the Greek name for the planet ().

Saturn’s rings are seen as viewed by NASA’s Cassini spacecraft, which obtained the images that comprise this mosaic at a distance of approximately 450,000 miles from Saturn April 25, 2007.
If you could somehow make it through all of that, then a blistering hot core made of iron and nickel awaits you at the planet’s center—along with a surprise, as scientists have yet to discover ...
