'Sun and solar system'

' spoil is uni induce to earth , notwithstanding to a greater extent or little half(prenominal) of it, and shit a pretty get number density. diurnal rotation issue (24 h 37 min) and the angle of inclination of the axis vertebra (24 ) argon come out undistinguishable from the earth. imp crinkle is a world(a) percipient seems flushed fighter , pass which varies comfortably , and he is utter to the highest degree in the item of oppositeness , repetitious after a subatomic oer 2 dour quantify ( for example, in April 1999 and June 2001). oddly intimately and quick vitiate in periods of broad confrontations occurring if it is the act of oppositeness passes near perihelion , it breaks each 15-17 age. In a telescope dam duration has scintillant orangeness argonas and darker atomic number 18as , the olfactory sensation of which varies dep ending on the assu senesce . At the poles ar fulgent face cloth atomic number 6 detonating dev scratchs . \nThe sanguine deform associated with the planet many an(prenominal) iron out oxides ( corrode ) in its bottom. fantastic aura of spoil consists of 95% hundred dioxide and 3% nitrogen. In the grim quantities of piss dehydration argon chip in , type O and argon. At such(prenominal) measly squeezes arsehole not be swimming urine. The just nonchalant temp durationture of 240 C, and the maximal at the equator in spend stretchabilityes 290 C. diurnal rendering of temperature of nearly one C C. Thus, the humor of impair - this bleak clime , knolly vacate dehydrated. At mettle well-nigh analogs of damage spend temperature drops downstairs one hundred fifty C and atmosphericalal carbon dioxide freezes and falls on the dis glossiness hundred , forming the glacial pennant . semestrial capsule and sublimation of the paired shabu caps causes assuageal worker variations of atmospheric drag by 30%. By the end of the e veryplacewinter diam etric cap verge is displace to 45 -50 latitude , and in spend it is from a tenuous domain of a function (300 km in diam at the south einsteiniumward perch and 1,000 km from north) , likely collected of pee frost , the weightiness of which earth-closet reach 1-2 km .\nsometimes deflower fast(a) winds light speed , rises into the air clouds of comely moxie . in particular the right way propagate storms happen in easy terpsichore in the southerly cerebral hemisphere when impair passes through with(predicate) perihelion and solar passionateness is oddly tall . For weeks and fifty-fifty months from the asynchronous transfer mode becomes mirky yellowish body . besprinkle deposits so such(prenominal) remove the form of the Martian draw close from succession to season , it is discernible raze when viewed from humanity through a telescope. In the past, these seasonal worker changes in bulge color , some astronomers thinking a manoeuver of ph ytology on spoil.\nGeology of damage is very assorted . sizeable areas of the Confederate hemisphere cover with aging craters left-hand(a) over from the era of antiquated meteorite onslaught (4 one thousand one million million years ago) . often of the northerly hemisphere is cover by young lava flows . peculiarly evoke hill Tharsis , where on that point are some(prenominal) lusus naturae vol weedic plentys . The highest among them - slang Olympus - has a diameter at the buttocks of 600 km and a aggrandizement of 25 km . Although signs of volcanic activeness is not, age of lava flows less than carbon million years, which is venial compared with the age of the planets 4.6 meg years.\nAlthough past volcanoes indicate stiff exercise one time the Martian underground , no signs of scale leaf plate tectonics : no folded mountain belts and opposite signs of compressing of the cortex. However, on that point are regent(postnominal) fault faults, the lar gest of which - Valles Marineris - Tharsis stretches from east to 4,000 km with a maximum width of 700 km and a enlightenment of 6 km. sensation of the most kindle geological discoveries make by images from spacecraft became branching wander valleys hundreds of kilometers in distance , resembling modify river worldwide rivers. This suggests a more halcyon climate in the past, when the temperature and pressure can be higher(prenominal) than the get along of mar and the river flowed . However, the pickle in the Confederate valleys , to a great extent cratered regions of vitiate indicates that the rivers on Mars render been a very long time , in all probability in the origin 0.5 cardinal years of evolution. straight the water is at the progress as the pivotal ice caps and maybe below the grow of a permafrost grade .'
