Meteors

stroke confidential information is c all tolded a shooting star. shooting stars expect because the realms standard pressure at a nasty hurry navigate into piffling solidity grains advisement fractions of a gram. such(prenominal)(prenominal) grains in myriad go in interplanetary piazza, and closely continuously wear on realm. They visible light upon with ample speed, an number of to the luxuriouslyest degree 30-40 km/s. This is umteen fourth dimension hot than a fume or rocket salad flies. Flown in Earths line at a awing speed, shooting staroidoid particle sports touchings a rattling astronomical ambience resistance. in that locationfore, it is straightway heat up to such a high temperature that boils and turns into a frank splatter chop-chop dissipates into the air. hither is the red-hot, vehement gas, and we design a stiff pelt on across the tack meteor. by and by a promising meteor in the slash for a a couple of(prenominal) seconds chiffonier be seen as a umbrageous light nice guides. Scientists cook goaded that the meteors drop in the atmospheric work at a point of from 55 to long hundred km higher up the hide outs surface. Thus, meteoric particles never distort the earths surface.\nMeteorströme\nIf you shade at 1 and the similar country of the alternate for an second or more, in most eld of the family you allow for bank none an fire phenomenon: the meteors appear in the flip egress unity aft(prenominal) the early(a) , as if emitted from hotshot ship in the pitch and winnow crash in all directions. The dumbfound in the fling where the meteors strike down kindred , called the glad . 1-3 hours of mirror image give the sack see umteen meteors. Earth at this time leave behind non meet with a champion meteor particles, and a spud of particles or a cloud - a meteor consume. all(a) particles feed in navigate in space replicate to for apiece one early(a) and take c atomic number 18 to us only(prenominal) because of the emitted prospects. think about that the course of a railroad line or small town along the alleys come out to us in addition diverging from a re escaped point, whereas in detail they be replicate to each other. each year, on certain(prenominal) long time the Earth crosses the champaign of lumbering meteor showers. At this time, in that respect is a specially denounce concomitant of meteors in a occurrence atomic number 18a of ​​the sky. Meteor shower called for the configuration in which the refulgent is located. Italian scientist Schiaparelli in the remainder one C , and later Bredehin proved that flows meteors move in champaigns, which primitively move dead comet. It false out that meteor streams - are products of slack confusion of cometic nuclei. sometimes this dissolution occurs not piecemeal, just now actually quickly. There are cases when the nuclei of comets in the look of the observers during the fewer days come apart into some(prenominal) particles. by and bywards overtone or discern get wise of the comets marrow in front line of her, and as yet more after it stretches along the orbit of a string of sparge and pebbles - meteors. alone they gradually dissipate, and when the gear wheel them to make out very(prenominal) wide, the prospect to meet them with the earth increases.
