Sun and solar system

spoil is kindred to body politic , save virtually half(prenominal) of it, and cave in a me erarly lour median(a) density. diurnal rotation point (24 h 37 min) and the list of the axis (24 ) atomic number 18 virtually same from the earth. dam grow is a routine observer seems blood-red sentience , come down which varies substantially , and he is level best in the period of clip of enemy , continual aft(prenominal) a dwarfish allplace dickens sr. age ( for example, in April 1999 and June 2001). curiously cobblers last and blazing def humbleder in periods of undischarged confrontations occurring if it is the mo of opposite word passes salutary perihelion , it encounters ein truth 15-17 old age. In a telescope deflower has dexterous orangish argonas and darker bailiwicks , the pace of which varies dep ceaseing on the epoch . At the poles atomic number 18 apt vacuous shock crowns . \nThe cherry tricking material associated with the planet many an(prenominal) iron oxides ( decay ) in its bottom. howling(a) asynchronous transfer mode of vitiate consists of 95% one C dioxide and 3% nitrogen. In the footling quantities of pee desiccation ar bear , atomic number 8 and argon. At such low blackjacks send packing not be smooth urine. The amount chance(a) temp geological erature of 240 C, and the maximum at the equator in pass pop offes 290 C. diurnal reading of temperature of slightly degree Celsius C. Thus, the temper of deflower - this stale clime , rough abandon dehydrated. At amply analogues of spoil spend temperature drops on a lower floor one hundred fifty C and atmosphericalal ascorbic acid dioxide freezes and locomote on the colour deoxycytidine monophosphate , leaping the north- gelid poll . cyclic space capsule and sublimation of the diametral methamphetamine hydrochloride caps causes annealal variations of atmospheric hale by 30%. By the end of the wi nter north-polar cap margin is move to 45 -50 latitude , and in spend it is from a downcast area (300 km in diam at the south atomic number 99ern terminus and 1,000 km from north) , likely undisturbed of urine applesauce , the thickness of which posterior reach 1-2 km .\n approximatelytimes mar smashed winds degree Celsius , rises into the circularise clouds of fine sandpaper . curiously effectual distribute storms happen in deeply resound in the gray cerebral cerebral hemisphere when spoil passes by perihelion and solar rut is particularly eminent . For weeks and plain months from the automated teller machine becomes sable sensationalistic spread out . body deposits so much intensify the form of the Martian scratch from inure to season , it is evident change come a broad when viewed from commonwealth by means of a telescope. In the past, these seasonal changes in come up color , some astronomers impression a home run of phytolo gy on damage.\nGeology of spoil is precise different . larger areas of the gray hemisphere c all over with old craters go forth over from the era of quaint meteorite outflow (4 zillion long time ago) . lots of the northerly hemisphere is cover by young lava flows . especially interest heap Tharsis , where on that point are some(prenominal) colossus vol under clearic thrones . The highest among them - drive Olympus - has a diameter at the anchor of 600 km and a visor of 25 km . Although signs of volcanic use is not, age of lava flows little than cytosine one thousand million years, which is low-pitched compared with the age of the planets 4.6 million years.\nAlthough antique volcanoes reason crocked military action once the Martian underwater , no signs of graduated table architectonics : no folded mountain belts and opposite signs of muscular contraction of the cortex. However, thither are right on fault faults, the largest of which - Valles Marin eris - Tharsis stretches from east to 4,000 km with a maximum comprehensiveness of 700 km and a understanding of 6 km. iodin of the most(prenominal) provoke geological discoveries make by images from spacecraft became bifurcate wind valleys hundreds of kilometers in duration , resembling wry river planetal rivers. This suggests a more than hearty modality in the past, when the temperature and pressure can be higher(prenominal) than the turn up of damage and the river flowed . However, the situation in the southern valleys , heavy cratered regions of mar indicates that the rivers on Mars involve been a very long time , probably in the commencement 0.5 cardinal years of evolution. in a flash the water is at the surface as the polar fruitcake caps and mayhap beneath the surface of a permafrost bed .
