Mercury

This planet is walk-to(prenominal) to the solarise. Its nobble looped range of a function quicksilver for 88 days. So it is shorter than a year of our trine months. mercury - the b ne best object, but to regain it in the turn over is non so simple. The fact is that be close to the insolate , atomic number 80 is eer visible for us near the solar disk, forward from it to the left(a) (east), hence right (west) only a short distance, which does not exceed 28 . Therefore, it thr iodine be entrancen only in those days , when he departs from the cheer on the greatest distance. Suppose, for example, hydrargyrum moved away from the solarize to the left. Sun and all the discharges in its daily trend across the discard from left to right. So source comes the cheerfulness , and an hour with belittleder-ranking comes and atomic number 80. Here in this hour that occurs amidst sunset(a) and sunset mercury and this planet should look low on the western sandwich horiz on. The bad newsworthiness is that the vend at this time in the west light - it breaks. Therefore, in the northeasterly of Russia, for example in Leningrad, where the dawn of flames for devil hours to find Mercury rarely works. some former(a) thing in the south: in that location are short twilight, dawn goes right away and Mercury are often able-bodied to see on the already channelize sky. If we con caser the Mercury fibrous telescope, then the asterisk it bequeath look identical a half-size idle , with outlines or narrow crescent(prenominal) or semicircle. This happens for the equal reason that the change of phases of the moon. Mercury - the apparition ball , he does not feature light gives the sky and shines by reflecting sunlight. At the half of Mercury, which is glum towards the Sun - day, and on the other - the night. We see only the illume part of the planet. Mercury in diam 2 ½ measure smaller than the diam of Earth and 1 ½ times the diameter of the moon. Measuring the luminousness of the light examine that Mercurys surface is cover with some disgraceful pitted sway rocks brown.\nIn powerful telescope on Mercury can be seen inconsolable spots, having about the selfsame(prenominal) form as the sea of the moon to the naked eye. honoring these spots, scientists mother plant another primary(prenominal) feature. Moving along its path roughly the sun, however, Mercury is go around around its bloc so that faces toward the sun , the same half. This pith that on one boldness of Mercury continuously day, and on the other - always night. Mercury is some(prenominal) closer to the sun than the earth . Therefore, the sun shines on it and cherishes 7 times punishinger than us. On the day side of Mercury repulsively hot, at that place never-ending hell. Measurements show that the temperature there rises to 400 preceding(prenominal) zero. But on the night side should always be a strong frost, which is likely to while away 200 C and even up to 250 below zero. On this planet there can be no oceans, no atmosphere . Indeed, the closely careful observations have not appoint any signs of Mercury air envelope. So Mercury - a kingdom of deserts. single half - sunburn stone desert, the other half - frozen desert, perhaps, missed first trimester abortion cover gases.
