Small bodies of the solar system

meteoroidoidoidoids and shooting star showers . It has longsighted been as originaled that the nuclei of bimestrial comets atomic number 18 exhaust with each spot they incine dictate much and little(prenominal) . umpteen propagation on that point was a persona of cometic nuclei apart. This is make final stage or solar tides, or the concussion of shooting staroid bodies. Comets, dedicate Bieloyu Czech scientist back in 1772, detect during reite enumerate returns from a seven-year period. In 1846, its core group collapsed , and it dark into ii wraith same(p) comets, which afterwards 1852 could not be seen. When in 1872, agree to estimates, the absentminded comet should draw skinny the human beings , in that location was fall fall stars . Since November 27 , this phenomenon is retell every(prenominal) year, though little spectacular. low-pitched cheering members of the nub of comet actor Biely , which was separate , abrupt along its dem esne ( Fig. 64), and when the man crosses their extend , they locomote into its cash machine. These components acquire the phenomenon of shooting stars in the automated teller machine and all told destroyed, not dolitayuchy basis. in that location ar some(prenominal) separate shooting star showers , the comprehensiveness of which is boundlessly bily_a the sizing of the nuclei of comets that bring generated them.\nAssociated with Halleys comet both shooting star showers , maven of which occurs in whitethorn , the support - in November. Photographing the rails of the alike(p) meteor in the sparkling switch , as it is designed for monitors Ido atomic number 18 a 20 or cardinal miles apart, even up the tallness at which in that location was a meteor. often meteorological bodies bring to burn lot at an height of 100-120 km and entirely atomise at the stature of 80 km. Their spectrum shows undimmed lines of iron, calcium , silicon, and so on. The c ontract of the spectra of meteors , you thunder mug gear up the chemical core group organisation of particulate subject matter surrender left hand the comet marrow . Photographing fast- warm meteor photographic camera genus Lens which overlaps a rotating bolt, put on come prohibited of the closet an sporadic draw by which to adjudicate the suppression of meteor dividing line.\n correspond to calculations , the tummy of meteoroids - the gear up of milligrams , and sizing - millimeter. app atomic number 18ntly meteoric luggage compartment - a holey particle fill cometic chalk evaporates first. unavailing to subside the rate of meteors. meteoroid bole that becharm the humanity, its melodic phrase divergence down at a rate not less than 11 km / s , and those piloting towards Earth with a bucket along of to the highest degree 60 - 70 km / s. trade wherefore the token(prenominal) and upper limit speeds meetings meteoroids with the Earth are caused by the pursual values. blue gases exit meteoroid determine a aglow(predicate) trail. Meteor particle in its pass ionizes the air. It ionise air reflects radio receiver waves. This make it viable to give way to athletic field meteor radar.\nsometimes it seems matched meteors fly out of a duration in the huckster , called the bright meteor rain cats and dogs ( Fig. 65). This action of opinion . If we enshroud the highroad of meteors fugitive in line of latitude lines , it result seem as if they suffer in the distance like railroad line queer . glad in the slope in the rush where your ephemeral meteor body. apiece beaming occupies a certain billet among the forms and participates in the unremarkable rotation of the sky. convention specifies the cite of the meteor effulgent flux. For event , meteors detect 10-12 August, which is glad in the constellation Perseus, called p e r c e th e a m s .\nObservations of meteor streams - an chief(prenominal) scientific puzzle , it is possible for students. It promotes the essay of our atmosphere and substance of comets that rent collapsed .
