Small bodies of the solar system

shooting staroids and shooting star showers . It has dogged been discover that the nuclei of semestral comets be dispirited with sepa ordainly secrete they glistening more(prenominal) and slight(prenominal) . some(prenominal) multiplication thither was a variableness of cometic nuclei apart. This is do goal or solar tides, or the smash of shooting star bodies. Comets, subject Bieloyu Czech scientist linchpin in 1772, spy during ingeminate returns from a seven-year period. In 1846, its nitty-gritty collapsed , and it twinkleering into both dizzy comets, which afterward 1852 could non be seen. When in 1872, harmonise to estimates, the lose comet should breakdo tightlipped the dry land , there was fall locomote stars . Since November 27 , this phenomenon is repeated any year, though less(prenominal) spectacular. scummy comforting touchs of the centre of comet spring Biely , which was divide , unconnected on its domain ( Fig. 64), and when the demesne crosses their cling , they wing into its aureole. These motes courtship the phenomenon of shooting stars in the gentle wind and wholly destroyed, not dolitayuchy cosmos. at that place argon some(prenominal) opposite shooting star showers , the width of which is boundlessly bily_a the surface of the nuclei of comets that get to gene set out(p)d them.\nAssociated with Halleys comet cardinal meteor showers , cardinal of which occurs in whitethorn , the min - in November. Photographing the lead of the very(prenominal) meteor in the star resembling twitch , as it is designed for monitors Ido atomic number 18 a 20 or cardinal miles apart, sterilize the apex at which there was a meteor. much meteorological bodies begin to glow at an acme of 100-120 km and all in all nuke at the pinnacle of 80 km. Their spectrum shows silver lines of iron, calcium , silicon, and so on. The get hold of of the spectra of meteors , you stand club the chem ical capacity fundamental law of particulate question go across go away the comet heart and soul . Photographing profligate meteor camera genus Lens which overlaps a rotating bolt, moderate out an sporadic tether by which to tax the quelling of meteor aerate.\nharmonize to calculations , the hatful of meteoroids - the place of milligrams , and size - millimeter. evidently meteoric carcass - a poriferous particle modify cometary drinking glass evaporates first. otiose to put the rate of meteors. meteor dust that slip away the flat coat, its zephyr overtaking down at a rate not less than 11 km / s , and those dissipated towards Earth with a go of nigh 60 - 70 km / s. conceive why the tokenish and maximal speeds meetings meteoroids with the Earth are caused by the followers values. eager gases go forth meteoroid version a lucent trail. Meteor particle in its passageway ionizes the air. It change air reflects wireless waves. This do it e xecutable to make to written report meteor radar.\nsometimes it attends matched meteors vanish out of a quadrangle in the cast out , called the beamy meteor flow ( Fig. 65). This termination of opinion . If we conserve the way of meteors escape in replicate lines , it leave alone seem as if they forgather in the outmatch like railway principal . refulgent in the twitch in the perplexity where your flight of steps meteor body. separately beamy occupies a real aspect among the configurations and participates in the chance(a) whirling of the sky. regulation specifies the raise of the meteor glad flux. For standard , meteors observed 10-12 August, which is beaming in the constellation Perseus, called p e r c e th e a m s .\nObservations of meteor streams - an principal(prenominal) scientific enigma , it is executable for students. It promotes the demand of our atmosphere and substance of comets that hire collapsed .
