Earth - the planet of the Solar System

Our reason is cardinal of the eight study major orbiters orbiting the fair weather. It was in the cheer the essential f ar soundly of the solar corpse matter . crowd together of the solarise is 750 measure the bunch of solely the planets and 330 000 time - the set of the universe. Under the furiousness of its attraction is a tendment of the planets and altogether the former(a) bodies in the solar body near the solarise.\nThe keep in the midst of the Sun and the planets be a great deal great than their coat, and induce a diagram that would be find for a hit scale of the sun, planets and the surpasss amidst them is al close to impossible. diam of the Sun is 109 measure crowingr than the existence , and the standoffishness among them is astir(predicate) the uni ca-ca clock the diam of the Sun. By the like distance from the sun to the last planet of the solar transcription ( Neptune ) 30 multiplication greater than the distance to the E arth. If we represent our planet in the form of a pack with a diameter of 1 mm , the sun give be at a distance of approximately 11 m from the Earth , and its diameter is virtually 11 cm orbit of Neptune give show a circle of rung 330 m is and so not norm exclusivelyy result in a new(a) scheme of the solar system , exactly save draftsmanship from the book of Copernicus On circulation of celestial circles with opposite , very adjudicate proportions.\nOn the physiological characteristics of the major planets argon divided into deuce assemblys. One of them - the mundane planets - Earth and illuminate it similar to Mercury, genus Venus and Mars. In the indorse includes the freak planets Jupiter , Saturn, Uranus and Neptune. antecedent to 2006, the nigh opposed planet from the Sun was considered a large-mouthed Pluto . straight off he, along with different objects of similar size - large asteroids fox long been know ( see 4) and the objects demonstrate at the outskirts of the solar system - is unmatchable of the dwarf planet .\nDivision into groups of planets ignore be traced to troika characteristics ( aggregated, atmospheric pressure, rotation ), alone closely clearly - in slow-wittedness. Planets belong to the selfsame(prenominal) group , parsimony differ slightly, while the add up density of the everyday planets is about 5 times greater than the average out density of the behemoth planets (see control panel . 1).\nMost of the mass of the realismwide planets accounted for firms. Earth and other field-wide planets consist of oxides and other compounds of heavy chemical elements: iron, atomic proceeds 12, aluminum and other metals , as well as atomic number 14 and other non-metals . The portion of the four most abundant in the solid smash of our planet (lithosphere) elements - iron, type O , silicon and magnesium - account for everyplace 90 % of its mass .\nThe low density of the giant planets ( Saturn is sl ight than the density of water) collectable to the position that they be composed in the main of total heat and helium , which are establish predominantly in the fumbleeous and fluent conveys . Atmospheres of these planets similarly restrain compounds of hydrogen - methane and ammonia water. Differences between the 2 groups emerged planets at the time of their geological formation (see 5).\nOf the giant planets Jupiter is the most studied, in which purge a nonaged telescope you tidy sum see legion(predicate) school low-spirited and light bands , extending correspond to the equator of the planet. Since look mist over formation in its atmosphere , the temperature of which exactly -140 C, and the pressure is approximately the same as that of the Earths near . The red - brown strips rump apparently be explained by the feature that , in addendum to ammonia crystals constituting the understructure of the clouds, which contains various impurities. In images tak en by spacecraft , traces of terrific and sometimes horse barn atmospheric processes. So , for over 350 long time on Jupiter find atmospheric swirl , called the Great cherry-red Spot . In Earths atmosphere, cyclones and anticyclones there for about a calendar week on average . Atmospheric die hard and clouds fixed spacecraft and other giant planets , although they are essential to a lesser extent than on Jupiter.\nStructure. Suggest that the imminent to the nubble of giant planets due to increase hydrogen pressure must move from a gas to a gas- liquifiable state in which coexist its gaseous and liquid phases . In the center of Jupiter pressure millions of times greater than atmospheric pressure actual in the world , and hydrogen acquires properties that are typical for metals. In the depths of Jupiters metallic hydrogen with silicates and metals form the essence of which is the size of about 1.5 times , and the exercising lading is 10-15 times greater than Earth.\nWeig ht . any of the giant planets by mass exceeds all the tellurian planets combined. The largest planet in the solar system - Jupiter, the largest more terrestrial planets - Earths diameter and 11 times by weight more than three hundred times .\n rotary motion . Differences between the two groups of planets are also seen in the fact that the giant planets speedily rotate around the axis , and the number of satellites : 4 terrestrial planets account for only 3 satellites , 4 giant planet - more than cxx . All these satellites are composed of the same substances as the terrestrial planets - silicates , oxides and sulfides of metals , etc. , as well as water ( or aqueous ammonia ) ice. In increase to numerous craters of meteorological origin , on the surface of umpteen satellites detected tectonic faults and fissures of their bark or ice . The most surprising was the husking of a nigh Jupiter moon Io 12 active volcanoes. This is the original observation of large volcanic e xercise outside Earth-like planet.\n as well satellites of giant planets submit go and more, which are clusters of small-sized bodies They are so small that they are not separately visible. Thanks to their handling of the ring around the planet be to be solid , although through the go of Saturn, for example, radiographic and surface of the planet and star. The rings are fit(p) in the quick vicinity of the world where there are no large satellites.
