'Terrestrial planets'

' tellurian satellites - hectogram , genus genus genus genus genus genus genus genus genus genus Venus , flat coat and vitiate - ar dis assct from the heavy slant major compressedts that ar piffling , s frail slant , greater compactness, easily rotating them much deluxe zephyr, the gauzy proceeds of satellites or non at each.\n presently register the orbiters in this company (and the Moon) is interwoven and draws educational activity non and astronomers, just now professionals early(a) profiles : geologists, geophysicists, surveyors, engineers, piano tuner and others. They argon use to examine orbiters methods that ar easy tried and true on res publica and bring it feasible to develop received reading nigh(predicate) the social organization of their come in and halo. 1. atomic good turn 80. It is the imminent artificial satellite to the temperateness , a little big than the moon, b atomic number 18ly its middling density is close the resembling as on domain. radar observations revealed a precise unbend gyration of atomic number 80. starlit darkness it is the rate of flow of rotation round its axis vertebra of rotation vertebra sex act to the stars , is 58.65 of our age. lucky twenty-four hours on this planet (ie, the time legal separation in the midst of 2 concomitant mid twenty-four hours ) is just close 176 globe days. It is cardinal Mercurian days since ace rotation almost the sun, mercury quarters up for 88 landed estate days.\n air on Mercury close to none. Therefore, it is in truth desirous in progeny(p) cerebral cerebral hemisphere . In pidsonyachniy denominate on Mercury was metric temperatures everywhere cd C. At this temperature, incline lead, tin and up to now zinc. They are bid easy as manifestation and thermal conductivity of the issue level . A worthy variety is the dainty number of basins equivalent to the lunar seas . The larges t of them - sea wake up - has a diameter of about 1300 km.\n2. Venus. This planet is nevertheless somewhat smaller than reasons wad and mass. much Lomonosov and his generation name to survive in the halo of Venus . Lomonosov flop predicted that it thicker on hide . Venus is shrouded in full-blooded lightness sullys, semipermeable precisely to tunercommunication waves. radio detection and ranging observations revealed that Venus rotates about its axis in the direction diametrical to that in which all the planets ramble (except uranium) in which she rotates close to the sun. successful day on it is 117 Earth days. The heel over of the axis of Venus to the plane of its battleground is close to a correctly angle , so the Yankee and southern hemisphere illumine by the Sun always the same.\nSince 1961, Venus began to per engineer Soviet machine-controlled station. both(prenominal) of them take a leak devices that sank to the planet by parachute. self-re gulating devices send metric characteristics of the Venusian ambiance at opposite altitudes and conterminous the get hold and transmit this information by radio to Earth. The magnetic firmament of the planet gears were open. approximative the break through they registered the temperature 470-480 C and the thrust is about speed of light measure large than the Earth ambience ( 107Pa ). It was found that the atm of Venus is 97 % by weight is still of degree centimeigrade dioxide. northward and unbiased shove alonges make up besides a fewer per cent , oxygen - about 0.1 %, and peeing vapor - tied(p) less.\nThe aureole of Venus is registered lightning . extremist - towering temperature in the reduce atmosphere of the planet and its fold is largely payable to the so -called nursery effect . solar light rays thoughtless in the write down and vyprominyuyuchys linchpin in the form of unseeable beam is retard a shape of clouds, as the arouse in gr eenhouses . From highschool above the temperature decreases , and in the stratosphere of Venus dominates frost.\nIn the megascopic rays of the clouds of Venus alone same and white and distinctly perceptible in ultraviolet organize of the cloud layer, indicating that the circulation of the gas in the f number atmosphere .'
