Saturn's radiation belts. Saturn has relatively weak radiation belts, because energetic particles are absorbed by the moons and particulate material orbiting the planet. [47] The densest (main) radiation belt lies between the inner edge of the Enceladus gas torus at 3.5 R s and the outer edge of the A Ring at 2.3 R s.
Saturn is the most distant of the five planets easily visible to the naked eye from Earth, the other four being Mercury, Venus, Mars, and Jupiter. (Uranus, and occasionally 4 Vesta, are visible to the naked eye in dark skies.) Saturn appears to the naked eye in the night sky as a bright, yellowish point of light.
Radiation belts have been detected at Jupiter, Saturn, Uranus and Neptune through in-situ observations, such as by Galileo (spacecraft) and Juno (spacecraft) at Jupiter, Cassini–Huygens at Saturn and fly-bys from the Voyager program and Pioneer program.
The American aerospace engineer and author Robert Zubrin identified Saturn as the most important and valuable of the four gas giants in the Solar System, because of its relative proximity, low radiation, and excellent system of moons. He also named Titan as the most important moon on which to establish a base to develop the resources of the ...
Cassini–Huygens (/ k ə ˈ s iː n i ˈ h ɔɪ ɡ ən z / kə-SEE-nee HOY-gənz), commonly called Cassini, was a space-research mission by 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.
Saturn's hexagon is a persistent approximately hexagonal cloud pattern around the north pole of the planet Saturn, located at about 78°N. [1] [2] [3] ...
It passed within 500 km of Rhea's surface, downstream of Saturn's magnetic field, and observed the resulting plasma wake as it had with other moons, such as Dione and Tethys. In those cases, there was an abrupt cutoff of energetic electrons as Cassini crossed into the moons' plasma shadows (the regions where the moons themselves blocked the ...
Saturn eclipses the Sun, as seen from the Cassini space probe.The forward scattering of light makes the faint outer rings more visible.. Forward scattering is the deflection of waves by small angles so that they continue to move in close to the same direction as before the scattering.
