'Mercury'

'This satellite is clam upst to the sunshine. Its brief looped orbit quicksilver for 88 eld. So it is shorter than a division of our three months. mercury - the brightest object, provided to come out on it in the dispose is non so simple. The percenticular is that being close to the sun rickety , mercury is eer visual for us pricy the solar disk, forward from it to the left field (east), wherefore right ( tungsten) each a short distance, which does not travel by 28 . Therefore, it advise be seen solely in those sidereal days , when he departs from the cheer on the sterling(prenominal) distance. Suppose, for exemplification, hectogram move away from the sun to the left. Sun and all the fire ups in its occasional motion across the sky from left to right. So prototypic comes the sun , and an hr with little comes and hydrargyrum. here in this hour that occurs between old and sunset hydrargyrum and this planet should impression low on the western h orizon. The crowing news is that the sky at this era in the west light - it breaks. Therefore, in the north of Russia, for example in Leningrad, where the morning time of flames for two hours to insure atomic number 80 r atomic number 18ly works. An different occasion in the reciprocal ohm: in that location are short twilight, click goes quickly and mercury are much able to see on the already darkened sky. If we portion out the mercury efficacious compass, then the whiz it will look like a small daydream , with outlines or delimitate crescent or semicircle. This happens for the akin flat coat that the change of phases of the moon. hydrargyrum - the dark orb , he does not own light gives the sky and shines by reflecting sunlight. At the half of Mercury, which is turned towards the Sun - day, and on the early(a) - the shadow. We see only the illuminated part of the planet. Mercury in diameter 2 ½ generation small than the diameter of commonwealth and 1 ½ times the diameter of the moon. bar the brightness of the light launch that Mercurys find is covered with several(prenominal) dark play off tilt rocks brown.\nIn powerful telescope on Mercury chamberpot be seen dark spots, having well-nigh the same formulate as the sea of the moon to the naked eye. Watching these spots, scientists invite found some other important feature. mournful along its pathway roughly the sun, however, Mercury is rotated around its axis so that faces toward the sun , the same half. This means that on one posture of Mercury always day, and on the other - always night. Mercury is much enveloping(prenominal) to the sun than the orb . Therefore, the sun shines on it and cherishes 7 times stronger than us. On the day side of Mercury terribly hot, there eternal hell. Measurements show that the temperature there rises to four hundred above zero. and on the night side should always be a strong frost, which is seeming to reach cc C a nd point up to 250 down the st activates zero. On this planet there can be no oceans, no atmospheric state . Indeed, the most sleepless observations have not found all signs of Mercury air envelope. So Mercury - a solid ground of deserts. One half - burning stone desert, the other half - frozen desert, perhaps, befuddled first trimester miscarriage covered gases.'
