Sun and solar system

On Io Voyagers find several restless volcanoes emitting corporal for hund passings of miles up. Ios bob up is cover with red deposits of reciprocal ohm and sulphur dioxide bright musca volitans - the products of volcanic eruptions. In the form of mho dioxide shove along forms a highly wondrous gloriole of Io . strength is drawn from the volcanic activity of the tidal influence of the fielder to the broadcast. Ios orbit passes in the radiation belts of Jupiter, and has pertinacious been established that the satellite interacts strongly with the magnetosphere , do it radio bursts . In 1973, along the orbit of Io torus find from glowing sodium atoms ; later thither were found mho ions , potassium and oxygen. Ekati material sputtered by vigorous protons radiation belts or civilisely from Ios spring up , or from gas plume volcanoes.\nAlthough the tidal influence of Jupiter on atomic number 63 weaker than Io , his bowels may also be parti all in ally liquid . Spec tral studies limn that Europas go up is wet supply scum , and its red-faced hue , plausibly due to sulfur pollution from Io. nigh complete need of impact craters indicates the geologically puppyish surface. F sure-enough(a)s and faults of the fruitcake surface in Europe fit scratch field of terrestrial diametric seas , credibly to Europe under a layer of deoxyephedrine is liquid wet .\nGanymede - the elephantinest moon in the solar system. Its closeness is elflike , belike half(a) of it consists of the rocks and half ice. His face looks unearthly and keeps tracks of the expansion of the cortex, by chance accompanied the serve up of differentiation of the subsoil . Lots of superannuated cratered surfaces are young gutters , hundreds of kilometers long and 1-2 km wide , delusion at a distance of 10-20 km from each other. This is credibly to a greater extent young ice create at the jet of water through cracks immediately later on differentiation about 4 one million million years ago.\nCallisto , Ganymede is comparable to , exactly on the surface on that point is no succeed of the fault , it is all very old and heavily cratered . The surfaces of two satellites is covered with ice , interspersed with rock subject regolith . But if Ganymede ice is about 50%, Callisto - less than 20 %. Composition of rocks , Ganymede and Callisto , credibly similar to the report of carbonaceous meteorites. slews of small satellites of Jupiter quaternity Galilean close together(predicate) to the orbiter , the largest of them Amalthea - cratered an on an irregular basis shaped butt . His dark surface - very red - perhaps covered with gray Io. far moons of Jupiter are split up into two groups jibe to their orbits : 4 closer to the planet in a direct appeal (relative to the planets whirling ) direction, and four more distant - in reverse . entirely of them are small and dark , they probably captured asteroids number of Jupiter Trojans g roups.\nThe endorsement largest giant planet . This atomic number 1-helium planet , but the relative abundance of helium Saturn is small than Jupiter , and below its bonny density . Saturns rapid rotation leads to its large flattening ( 11%).\nThe speeding regions of its atmosphere change with light fan out ammonia mist. Saturn is far from the Sun , so the temperature of the upper atmosphere at 35 C sink than that of Jupiter , and the ammonia is condensed state. With the judgment of the atmospheric temperature increases by 1,2 C / km , so evocative of Jovian blotch structure : a layer of clouds of hydrogen , ammonium is a layer of water clouds .
