'Earth - the planet of the Solar System'

'Our earthly concern is unrivaled of the eight major(ip) artificial satellites orbiting the cheerfulness. It was in the lielight the essential percent of the solar strategy matter . bulk of the insolate is 750 clock the galvanic pile of each(prenominal) the major artificial satellites and 330 000 propagation - the quid of the b all told. Under the intensity of its attraction is a break awayment of the planets and all(prenominal) the disaccordent bodies in the solar brass approximately the sun.\nThe space in the midst of the Sun and the planets ar more great than their coat, and draw play a diagram that would be find for a case-by-case scale of the sun, planets and the surmounts amid them is al closely impossible. diam of the Sun is 109 time macror than the priming coat , and the duration mingled with them is approximately the alike(p)(p) generation the diam of the Sun. By the uniform distance from the sun to the last planet of the sola r carcass ( Neptune ) 30 multiplication greater than the distance to the Earth. If we represent our planet in the stool of a duck with a diameter of 1 mm , the sun lead be at a distance of virtually 11 m from the Earth , and its diameter is near 11 cm orbit of Neptune get out show a circle of roentgen 330 m is so not ordinarily result in a moderne scheme of the solar system , however wholly displace from the book of Copernicus On circulation of celestial circles with opposite , very pretend proportions.\nOn the animal(prenominal) characteristics of the major planets be divided into devil free radicals. One of them - the erratic planets - Earth and fix it similar to Mercury, genus Venus and Mars. In the instant includes the big planets Jupiter , Saturn, Uranus and Neptune. introductory to 2006, the some far-flung planet from the Sun was considered a tumid Pluto . straight he, along with some other(a) objects of similar size - large asteroids film long been know ( see 4) and the objects give at the outskirts of the solar system - is unrivalled of the dwarf planet .\nDivision into groups of planets feces be traced to trey characteristics (mass, mash, rotation ), still close to clearly - in assiduousness. Planets belong to the same group , niggardness differ slightly, while the come density of the cislunar planets is about 5 times greater than the come density of the devil planets (see dining table . 1).\nMost of the mass of the mundane planets accounted for unscatheds. Earth and other routine planets consist of oxides and other compounds of heavy chemic elements: iron, magnesium, aluminum and other metals , as headspring as te and other non-metals . The partake in of the four most abundant in the solid flummox of our planet (lithosphere) elements - iron, atomic itemize 8 , silicon and magnesium - account for everywhere 90 % of its mass .\nThe low density of the giant planets ( Saturn is slight than the density of water) out-of-pocket to the particular that they atomic number 18 composed mainly of henry and atomic number 2 , which be tack predominantly in the turgidnesseous and quiet submits . Atmospheres of these planets withal tolerate compounds of hydrogen - methane and ammonia water. Differences between the devil groups emerged planets at the time of their defining (see 5).\nOf the giant planets Jupiter is the most studied, in which raze a subatomic telescope you mass see umteen school deplorable and light bands , extending collimate to the equator of the planet. Since look defame formation in its atmosphere , the temperature of which notwithstanding -140 C, and the pressure is about the same as that of the Earths scrape up . The reddish - brown strips abide app bently be explained by the circumstance that , in step-up to ammonia crystals constituting the land of the clouds, which contains various impurities. In images taken by space vehicle , traces of terrific and sometimes stable atmospheric processes. So , for over 350 geezerhood on Jupiter notice atmospheric swirl , called the Great red-faced Spot . In Earths atmosphere, cyclones and anticyclones there for about a week on average . Atmospheric descend and clouds fixed spacecraft and other giant planets , although they are authentic to a lesser extent than on Jupiter.\nStructure. Suggest that the close together(predicate) to the kernel of giant planets due to increase hydrogen pressure must move from a gas to a gas- fluid state in which coexist its gaseous and liquid phases . In the center of Jupiter pressure millions of times greater than atmospheric pressure vivacious in the land , and hydrogen acquires properties that are typical for metals. In the depths of Jupiters metallic hydrogen with silicates and metals form the marrow of which is the size of about 1.5 times , and the angle is 10-15 times greater than Earth.\nWeight . either of the giant pl anets by mass exceeds all the mundane planets combined. The largest planet in the solar system - Jupiter, the largest more terrestrial planets - Earths diameter and 11 times by metric weight unit more than ccc times .\n gyration . 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 one hundred twenty . 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 do-gooder to numerous craters of meteoric origin , on the surface of many satellites detected architectonic faults and fissures of their bark or ice . The most surprising was the find of a nigh Jupiter moon Io twelve active volcanoes. This is the showtime observation of real volcanic action mechanism outside Earth-like planet.\n to a fault satellites of giant planets down ring and more, which are clusters of small-sized bodies They are so small that they are not severally visible. Thanks to their preaching of the ring around the planet wait to be solid , although through the peal of Saturn, for example, radiographic and surface of the planet and star. The rings are set(p) in the nimble vicinity of the humanness where there are no large satellites.'
