Hyperion is known satellites of Saturn from Saturn sixteenth near one: Orbit: 1,481,100 one thousand meters away from Saturn Satellite diameter: 286 one thousand meters (410 x 260 x 220) Quality: 1.77e19 kg In Greek mythology, Hyperion was a giant, the Asian and the son of Uranus, Helios father.

Hyperion is full of holes like a sponge, or the presence of living matter NASA scientists use the "Cassini" spacecraft on Hyperion recently conducted a probe, and took the photos, the detection results display, seven surface of Titan is filled with holes, looks like a "sponge", these holes may also contain hydrocarbons, a finding that indicates the presence of chemical substances necessary for life in the galaxy widely. From Radio Physics and Space Research Center at Cornell University scientist Peter Thomas and his colleagues published an article that seven surface of Titan about 40% of the regions were in the hole like in "Nature" magazine latest issue. As early as in 2005 to 2006, "Cassini" once several intimate contact Hyperion, and its detection. Thomas said that the location of this photo was taken, "Cassini" from Hyperion very close, porous structure shown in the photo is our first discovery, it has very important significance for the study of the Saturn family secret. Hyperion is the largest one in the solar system highly irregular (non-spherical) objects, whose orbits 1,481,100 km from Saturn, the period of revolution around Saturn is 21.3 days. Hyperion small size, the longest part is only 360 km long, but it is irregular satellites of Saturn's largest one, is also one of the celestial bodies in the solar system's largest irregular shape. Because Hyperion irregular shape, rotation confusion, porous surface, scientists had previously suggested that Hyperion may be peeled off from a larger celestial body down. Unlike other satellites of Saturn is Enceladus seven smaller albedo (.2 - .3), indicating that it is at least covered with a thin layer of dark material. New analysis from Cornell University scientists showed that Hyperion may accumulate material made up of tiny particles together. As the quality is too small, insufficient on their own gravitational compression, Hyperion retains the irregular shape. Large celestial bodies often become close under their own gravity, so nearly spherical shape. The porous structure is relatively soft, so meteorites on Hyperion traces than ordinary solid celestial bodies hit the crater formed to be deeper. Scientists estimate that Hyperion's density is 544 kilograms per cubic meter, nearly half lighter than water, which means it's mostly internal porous. The scientists in the study also found that Titan is the main component of seven ice and mixed with organic matter which impurities. This means that Hyperion is a "dirty ice sponge." Scientists believe that some of the other celestial bodies, including low-density small satellites of Saturn, including a number of close may have a porous structure, but it needs further observation verified. From NASA Ames laboratory and astronomer Del Crook Shaq (sound, Dale Cruikshank) said, "From the photo, the bottom surface of Hyperion these holes darkness, unable to determine its internal structure, which is the Iapetus and Phoebe in parts of the structure is very similar to most people interested in the Hyperion discovered hydrocarbons. 'Cassini' spacecraft returns Data show that the surface of Titan containing seven ice and dry ice (solid carbon dioxide), which in a very special way ice with ice mixed with ordinary, cold water in these regions exist in the form of crystals, very similar to the earth when These frozen molecules when exposed to ultraviolet light, form new molecules with biological significance, although this does not mean that we have found a life outside of Earth, but it further shows the basic chemicals needed for life in the universe is widespread. " Hyperion ice world Saturn from the Cassini spacecraft No. 7 satellite - Seven flew near Enceladus, Titan surface to reveal the details of the first seven, showing the cup-shaped meteorite hit the pit filled with hydrocarbons. This may indicate that, in our solar system exists substantially wider compounds necessary for life. On Titan Cassini spacecraft captured seven images, overlay material composition diagram of two parts area. Blue represents the most exposed water ice. Red "Dry ice" (i.e. carbon dioxide ice). Magenta said water plus carbon dioxide mixed. Yellow carbon dioxide mixed with substances not CBBC. Hyperion (Hyperion) is one of the larger satellites of Saturn, which is away from Saturn than the largest satellite - Titan farther (their orbital radii ratio of about 1.6) orbit around Saturn about 21.3 days turn around. Because Hyperion large orbital eccentricity (0.03) and by Saturn and Titan's gravity changes caused frequent changes its rotation period, which is very special for all satellites in the solar system. Hyperion roughly approximates 360 × 280 × 225-kilometer long triaxial ellipsoid, the quality of the 800 trillion tons. Its shape is irregular, which is caused by severe meteorite strike. Its surface seems oldest crater achievements, the largest meteorite hit the pit is about 120 kilometers in diameter, depth 10 km. Cassini spacecraft during September 2005 near fly from Hyperion, with a variety of instruments to detect its secrets, captured its crater features such as surface water ice and dry ice found (ie, carbon dioxide ice) and There hydrocarbons spectral characteristics of dark matter, drawing surface material distribution. Planetary scientists 柯雷萨恩克 (Dale Cruikshank) that is particularly interesting is the presence of hydrocarbons on Hyperion. Comet dust, meteorites, and the Milky Way were found in the compound of carbon and hydrogen atoms. These molecules are incorporated into the ice and exposed to UV light to form a new molecule with biological significance. But this does not mean that it found a life, but further stated, there is a broad universe of basic compounds necessary for life. The Cassini spacecraft's ultraviolet, visible and infrared imaging spectrometer shot seven Titan surface details, you can draw maps of mineral and chemical characteristics, confirms previous observations from Hyperion presence of frozen water found on Earth. And they found that ice water ice mixed with ordinary non-expected way. Like the surface of Titan in seven regions of the brightest displays with Earth-like crystals on frozen water.柯雷萨恩克 explained that the ice surface is Hyperion frozen mixture of water and organic dust, and ice is also significant. Previous spacecraft and other satellites of Saturn probe Jupiter's moons - Ganymede and Callisto are described, carbon dioxide molecule is "complicated", or attached to a variety of ways other surface materials.柯雷萨恩克 that we thought to be just an ordinary carbon dioxide evaporates from the surface of Saturn's satellites for a long time, but when they are attached to other molecules is much more stable. Cassini scientist Han Drix (Amanda Hendrix) that flew Hyperion Cassini also shows the ability to multi-band instrument, this is the first of Hyperion by UV detection, tell us confused Fengyun chemical differences satellites. Hyperion is a big durian Seven of the latest images of Titan, its surface covered with pits honeycomb body, looks like a giant durian. According to the "New Scientist" magazine recently reported that "Cassini" spacecraft recently discovered a strange phenomenon at 7:00 overflight --- Saturn's Enceladus satellite does not have a sustained rotation axis. Before "Cassini", "Voyager" spacecraft has photographed more than 20 pieces of Hyperion photos, but because of the distance, when scientists discovered a unique operation which failed to form the satellites. Up to now astronomers still unclear whether Hyperion is a celestial body other residue left behind by the sea in the scholars looked like Hyperion is the biggest piece of the solar system "cosmic debris", however, due to its vicinity lack of other piecemeal "detail", which in the end still can not figure out is how to form. Fengyun length of 360 km and a thickness of about 225 kilometers of satellite covered with craters of varying sizes, their exposure to the sun, only a quarter of the surface is reflected back into space, thus the lower its brightness , it is difficult to accurately their observations from Earth. From Hyperion appearance point of view, it is only in both directions of rotation can maintain a stable state (physicists called the asymmetric shape of the object of this rotator). However, due to the impact of the solar system planets and Saturn's other major satellites, rotating Hyperion very irregular, it is difficult to predict when it would be on a "day", when the "night." NASA released the 4th from Hyperion situation can be seen in this satellite image surface, different color photograph of the ground substance composed of representatives of the difference. The figure of the original image is Cassini on September 26 at 7:00 62,000 km from Titan precision camera. "Cassini" NASA, the European Space Agency and the Italian Space Agency in cooperation projects, October 15, 1997 launch from Cape Canaveral Air Force Base in Florida liftoff. After nearly seven years on July 1 to arrive at Saturn and entered orbit around Saturn. Flight 3.5 billion kilometers.
