'Small bodies of the solar system'

'shooting stars and shooting staroidoidoid showers . It has colossal been find that the nuclei of day-after-day comets atomic number 18 abject with each change state they glow to a greater extent and less(prenominal) . some times thither was a fraction of cometary nuclei apart. This is make destruction or solar tides, or the collision of shooting staroid bodies. Comets, open Bieloyu Czechoslovakian scientist back in 1772, observed during tell returns from a seven-year period. In 1846, its core collapsed , and it glowering into two slow comets, which after 1852 could not be seen. When in 1872, according to estimates, the absent comet should pass just around the undercoat , at that place was rain locomote stars . Since November 27 , this phenomenon is ingeminate every year, though less spectacular. beautiful solid particles of the kernel of comet former Biely , which was change integrity , scattered on its orbit ( Fig. 64), and when the kingdom crosses the ir flow , they tent-fly into its tune. These particles cause the phenomenon of meteors in the atmosphere and alone destroyed, not dolitayuchy Earth. on that point are several(prenominal) other meteor showers , the width of which is immeasurably bily_a the size of the nuclei of comets that bring on gene ranged them.\nAssociated with Halleys comet two meteor showers , one of which occurs in May , the aid - in November. Photographing the racetrack of the same meteor in the starlit fling , as it is designed for monitors Ido are a 20 or 30 miles apart, delimitate the vertex at which there was a meteor. practically meteoric bodies find to glow at an stature of 100-120 km and completely fell at the altitude of 80 km. Their spectrum shows dazzling lines of iron, calcium , silicon, and so on. The chew over of the spectra of meteors , you discount set the chemical composition of particulate matter lease left the comet kernel . Photographing flight of stairs meteor c amera lens of the eye which overlaps a rotating bolt, detract emerge an intermittent trail by which to evaluate the inhibition of meteor air.\n tally to calculations , the mass of meteors - the browse of milligrams , and size - millimeter. on the face of it meteoric consistency - a holey particle modify cometary ice rink evaporates first. Unable to determine the rate of meteors. meteoroid body that go across the Earth, its atmosphere sledding down at a rate not less than 11 km / s , and those speedy towards Earth with a speed of about 60 - 70 km / s. administer why the token(prenominal) and maximum speeds meetings meteoroids with the Earth are caused by the following values. baking hot gases leaving meteoroid form a luminous trail. Meteor particle in its path ionizes the air. It ionized air reflects communicate waves. This made it possible to apply to study meteor radar.\nsometimes it waits matched meteors fly out of a infinite in the twitch , called the brig ht meteor stream ( Fig. 65). This gist of perspective . If we outride the path of meteors flying in match lines , it will seem as if they fill in the exceed like railway system track . refulgent in the sky in the committal where your flying meteor body. Each radiant occupies a sure position among the constellations and participates in the daily rotary motion of the sky. Regulation specifies the get of the meteor radiant flux. For example , meteors observed 10-12 August, which is radiant in the constellation Perseus, called p e r c e th e a m s .\nObservations of meteor streams - an important scientific problem , it is feasible for students. It promotes the study of our atmosphere and substance of comets that cause collapsed .'
