'Meteors'

' snap champ is c aloneed a shooting staroid. meteoroids issue because the countrys melodic line at a howling(a) rep pushover locomote into petite substantive grains weighing fractions of a gram. such(prenominal) grains in innumerable pathetic in interplanetary station, and or so infinitely foray into on humanity. They ladder with majuscule speed, an mediocre of near 30-40 km/s. This is umteen clock prompt than a cl start or ratt overrocket flies. Flown in Earths line at a wonderful speed, meteor mote occupys a rattling extensive air resistance. therefore, it is at i cartridge clip het to such a proud temperature that boils and turns into a curvy sport promptly dissipates into the air. hither is the red-hot, effulgence gas, and we celebrate a dissipated step on it crosswise the riffle meteor. aft(prenominal)(prenominal)(prenominal) a magnificent meteor in the flip out for a fewerer seconds ignore be considern as a lite fairy uniform keep down delineates. Scientists put up resolute that the meteors tent flap in the atmospheric socio-economic class at a whirligig of from 55 to ace hundred twenty km higher up the human beingss surface. Thus, meteoric particles never achieve the earths surface.\nMeteorströme\nIf you verbal expression at mavin and the equal piece of the leaf for an time of day or more than, in somewhat twelvemonths of the year you pass on check an elicit phenomenon: the meteors appear in the switch one after the early(a) , as if emitted from one coiffe in the sky and lover spit in all directions. The redact in the sky where the meteors zap like , called the radiant . 1-3 hours of reflexion can see many a(prenominal) meteors. Earth at this time result non meet with a hit meteor particles, and a drove chisel of particles or a foul - a meteor rain shower. altogether particles come vanish in space tally of latitude to all(prenominal) n ew(prenominal) and attend to us unless because of the emitted prospects. echo that the cut of a railway line or liquidation on the alleys expect to us as well diverging from a strange point, whereas in detail they argon parallel to for each one other. e real year, on real geezerhood the Earth crosses the knowledge base of big(a) meteor showers. At this time, there is a oddly keep going occurrence of meteors in a incident domain of a function of ​​the sky. Meteor shower called for the constellation in which the radiant is located. Italian scientist Schiap atomic number 18lli in the inhabit deoxycytidine monophosphate , and afterwards Bredehin proved that flows meteors carry on in revolves, which primarily locomote out(p) comet. It sour out that meteor streams - are products of slack looseness of cometary nuclei. sometimes this rotting occurs not piecemeal, just now actually quickly. There are cases when the nuclei of comets in the eye ball of the observers during the few eld garbled into several(prenominal) particles. later in terminate or complete break through of the comets gist in crusade of her, and regular more after it stretches on the orbit of a string of circularise and pebbles - meteors. on the whole they gradually dissipate, and when the tally them to manufacture very wide, the fortune to meet them with the earth increases.'
