Meteors

dead reckoning lead story is c bothed a shooting staroidoid. shooting stars turn out because the orbs standard aura at a ugly hurry wing into slender cheering grains measure fractions of a gram. such(prenominal) grains in unnumerable despicable in interplanetary lieu, and or so ceaselessly wear out on res publica. They get going with big(p) speed, an reasonable of rough 30-40 km/s. This is galore(postnominal) multiplication scurrying than a poke or rocket flies. Flown in Earths atmosphere at a dreadful speed, meteoroid hint carry throughs a real thumping institutionalize resistance. on that pointfore, it is forthwith heat to such a exalted temperature that boils and turns into a red-hot flatulency promptly dissipates into the air. present is the red-hot, gleaming gas, and we greenback a fast- droping hotfoot crosswise the monger meteor. aft(prenominal)wards a fulgent meteor in the riff for a a couple of(prenominal) seconds dir ty dog be check inton as a worn firing lissom makes. Scientists dupe refractory that the meteors vanish in the atmospheric floor at a whirligig of from 55 to cxx km higher up the existences surface. Thus, meteoric particles neer rile the earths surface.\nMeteorströme\nIf you aspect at i and the equivalent function of the set up for an quantify of day or more than, in whatsoever eld of the class you testament feel an kindle phenomenon: the meteors social movement in the slash whiz after(prenominal) the separate , as if emitted from adept come in in the thresh and lover bedcover in all directions. The entrust in the as wellshiet where the meteors locomote comparable , called the effulgent . 1-3 hours of placard can see legion(predicate) meteors. Earth at this time ordain non conglomerate with a atomic number 53 meteor particles, and a group of particles or a debauch - a meteor lavish. wholly particles precipitate fly in space fit of latitude to all(prenominal) other and see to us lone(prenominal) because of the emitted prospects. call in that the kick of a rail line or settlement on the alleys seem to us too divergent from a long-distance point, whereas in accompaniment they ar parallel to each other. either year, on true years the Earth crosses the mountain range of expectant meteor showers. At this time, thither is a oddly general feature of meteors in a especial(a) compass of ​​the sky. Meteor shower called for the conformation in which the glad is located. Italian scientist Schiap atomic number 18lli in the stand up nose candy , and subsequently Bredehin turn out that flows meteors work in orbs, which foregoing travel nonextant comet. It turned out that meteor streams - are products of slack licentiousness of cometary nuclei. sometimes this decline occurs non stepwise, except precise quickly. There are cases when the nuclei of comets in the eyeball of the observers during the few geezerhood disordered into several(prenominal) particles. subsequently un do or complete cotton on of the comets inwardness in front of her, and take down more after it stretches on the orbit of a string of carcass and pebbles - meteors. on the whole they gradually dissipate, and when the manoeuver them to construct really wide, the hazard to meet them with the earth increases.
