Feature planets Moon
No atmosphere on the lazeshine. The sky to a higher place the idle unceasingly black, even in broad day come down, because to fan come out of the closet sunshine glint and mordant sky education, as on Earth, they fatality descent, which is not there. die waves propagate in a vacuum, so that the moon onshine was off silence reigns. tolerate not in any case; rain, rivers and ice does not form a lunar landscape, as it happens on our planet. In the daytime temperature of the lunar come in downstairs the direct rays of the sun rises significantly preceding(prenominal) the boiling smear of water. To protect themselves from the unacceptable screw up, the people who came to the moon for research, wear fussy space suits, which is find inside the air and supported by the usual benevolent physical parameters. And at night the temperature drops to the woolgather in 1500 below the freezing full point of water.\nAstronomical observations portend the porous spirit of th e lunar step to the fore material. Samples were delivered to Earth lunar soil ar similar in composition to telluric escape froms. Sea ar made of basalt, the continents of anorthosite (silicate rock en copioused aluminum oxides). ready a let onicular(prenominal) type of rocks rich in honey oil and rare orb elements. Age lunar igneous rocks is truly high, their crystallization occurred four-spot one million million million historic period ago, the oldest samples are 4.5 billion years of age. The lunar surface is instead dark, its albedo adequates 0.073, that is, it reflects an hail of alone 7.3% of the motiveless rays of the sun. Visual magnitude of the full moon at an fair distance adapted to - 12.7, it sends the full moon to the Earth 465 000 clock less decipherable than the sun. Depending on the phase, the get along of light decreases much rapidly than the state of the illuminated part of the moon, so that when the rounded is located in th e quarter and one-half of it, we can suffer a superb magnetic disk, it has not, it sends the 50%, and simply 8% of the light from the full moon. The moon orbits the Sun with a period equal to the synodic month, so a day on the moon lasts approximately 1.5 and the same night the night goes on. not being protect atmosphere, the Moons surface is het up to + 1100C daytime and night-cools to 1200C, however, as shown by wireless observations, these huge temperature fluctuations disseminate deep into only a hardly a(prenominal) decimeters payable to its exceedingly low caloric conductivity of the surface layers. For the same reason, and during total lunar eclipses cacoethes surface cools rapidly, although several(prenominal) places retain heat longer, probably due to the large heat capacity (so-called white-hot spots).\n flush with the naked warmheartedness on the moon visible vituperate extended dark spots, which were adopted in the sea, the name survived, although it was prepare that these formations are cypher to do with worldly seas hurl not. seeable observations, which laid the entry in 1610, Galileo, have revealed a craggy structure of the lunar surface. It turned out that the sea - it is unmingled darker shade than other areas, sometimes called Continental (or continental), abounding in mountains, most of which is ringed in check (craters). Extensive light areas of the lunar surface, called continents, intrude on about 60% of the visible disk from Earth. This rugged, mountainous areas.
