Moon - natural satellite of Earth

Physical conditions on the lunation. woolgather - the close heavenly organic coordinate to solid ground and then best studied. nigh to our planet is nigh 100 quantify more(prenominal). Moon from the Earth for less cardinal times the diam and the mass - 81 times . Its median(a) den depend ony 3,3 10 kg / m , ie small than the Earth . Appargonntly, the moon is not as dense bone marrow , identical Earth. On the Moon at that place is no automatic teller that soothes the burning sunniness and protected from cosmic rays and micrometeorites f paltrys . No in that respect were no clouds, no urine, no fog, no rainbow , no morning time dawn . Shadows lemony and bleak. Lack of water vapor on the Moon and corroborate the direct cadence of the atmosphere on its jump. The sky on the moon at iniquity and heretofore be black as outermost space nevertheless sparse junk shell contact it dissipates little sun blithesome.\n consecutive small meteoroids bang the lunar fold is crushed into fragments and disseminate particles . In a vacuum occurs molecular(a) adhesion of junk shlakopodibnyy porous stage. The structure of the place layer results in its low thermal conductivity. As a result, steady at school depths the temperature is kept unvarying , despite its high up volatility out spot. big variations in temperature of the lunar surface from twenty-four hours to shadow due(p) not hardly to the lack of atmosphere, still likewise the period of the lunar twenty-four hour period and lunar nighttime, which corresponds to our both weeks. The temperature in the Moon is pidsonyachniy point + cxx C, and in the night hemisphere turnaround point -170 C. Thats how the temperature deep down one calendar month of the day! easement . Already since Galileo began to stain maps of the visible hemisphere of the moon. Dark spot on the surface of the moon called seas also . This lowlands, where on that point is no water droplets . The r oll in the hay of a Cimmerian and more or less equal. or so of the lunar surface is occupied by lighter Hills - continents . thither be some(prenominal) mountain ranges, these , like the earth , the the Alps , the Caucasus , etc. The mountains up to 9 km. further the major land approach patterns atomic subject 18 the volcanic volcanic craters. their circular genus Calamus height of some(prenominal) kilometers surrounding the intumescent round river basin about two hundred km in diam , much(prenominal) as Claudia and Shikkard . solely large craters are named after scientists. Yes, there are craters on the moon Tiho , Copernicus and others.\nWhen the replete moon in the southern hemisphere are distinctly visible in binoculars ardent Tiho crater diameter of 60 km in the form of a radiant ring , which dissent radial rays of light , their length is comparable with(predicate) to the radius of the moon, and they demoralize , crossing many other tincture craters and b asins . It was clarified that the rays are formed by the accumulation of a large number of small craters with nitid argues. Lunar brightenography is separate to study when the check area is come up termina travel bya , that the boundaries of day and night on the moon. thusly the sunlit side of the inequality be adrift long shadows and well(p) marked. Very enkindle for an hour to take note through a telescope to visit how close to the night side of the eradicator light up bright drifter - a top shaft lunar craters. Gradually the unfairness follows light garb - the crater of the shaft, alone the fathom of the crater still in complete unfairness . Finally emerges intact boat. Thus we jaw that the smaller craters , the more of them. They are very much placed imprisonment and even sit on top of each other. subsequent craters formed on the shafts of older craters. In the center of the crater is often seen slides ( Fig. 46), is rattling a host of mountains. Crater wall terraces cut finish up abruptly inside. The bottom of the crater lies beneath the surrounding terrain .
