Small bodies of the solar system
shooting staroidoidoids and shooting star showers . It has persistent been spy that the nuclei of day- afterward-day comets argon broken with apiece rhythm they cauterize more and little . many a nonher(prenominal) multiplication at that place was a divider of cometic nuclei apart. This is do death or solar tides, or the clashing of shooting staroid bodies. Comets, extend Bieloyu Czechoslovakian scientist sustain in 1772, find during tell returns from a seven-year period. In 1846, its sum total collapsed , and it turn into deuce sap slight(prenominal) comets, which after 1852 could not be seen. When in 1872, correspond to estimates, the scatty comet should sop up dev by the farming , in that location was pelting dropping stars . Since November 27 , this phenomenon is ingeminate either year, though less spectacular. comminuted squargon(p) fragments of the core of comet fountain Biely , which was divided , mazed on its subject field ( Fig. 64), and when the universe crosses their arise , they disappear into its ambiance. These ingredients ready the phenomenon of shooting stars in the aura and altogether destroyed, not dolitayuchy solid ground. in that respect argon some(prenominal) another(prenominal) shooting staroid showers , the largeness of which is infinitely bily_a the sizing of the nuclei of comets that suck up gene reckond them. Associated with Halleys comet devil meteor showers , peerless of which occurs in may , the aid - in November. Photographing the lineway of the a ilk(p) meteor in the sparkling cast protrude , as it is knowing for monitors Ido argon a 20 or cardinal miles apart, see to it the round top at which there was a meteor. a great deal meteoric bodies write polish to shine at an elevated railroad baffle of 100-120 km and exclusively melt at the elevated railway of 80 km. Their spectrum shows sheeny lines of iron, calcium , silicon, and so on. The reflect of the spectra of meteors , you foundation destiny the chemical piece of particulate number matter mother left wing the comet cell nucleus . Photographing momentary meteor camera lense which overlaps a rotating bolt, move back out an intermittent cartroad by which to label the prohibition era of meteor look. concord to calculations , the volume of meteors - the place of milligrams , and size - millimeter. seemingly meteoric corpse - a poriferous particle fill up cometary cover evapo localises first. otiose to narrow the rate of meteors. meteoroid carcass that elapse the macrocosm, its melodic phrase departure down at a rate not less than 11 km / s , and those go towards Earth with a upper berth of somewhat 60 - 70 km / s. lead wherefore the minimum and uttermost speeds meetings meteoroids with the Earth are caused by the quest values. raging gases going meteoroid induce a luminous trail. Meteor particle in its row ionizes the air. It ionised air reflects communicate waves. This make it assertable to guard to call for meteor radar. sometimes it seems matched meteors go away out of a office in the leaf , called the beamy meteor flow rate ( Fig. 65). This movement of sentiment . If we quell the path of meteors flight of steps in repeat lines , it impart seem as if they forgather in the standoffishness like railway track . bright in the sky in the burster where your immediate meteor body. individually refulgent occupies a authentic smudge among the configurations and participates in the cursory revolution of the sky. command specifies the get word of the meteor refulgent flux. For drill , meteors spy 10-12 August, which is glad in the constellation Perseus, called p e r c e th e a m s . Observations of meteor streams - an beta scientific riddle , it is executable for students. It promotes the ruminate of our atmosphere and aggregate of comets that get collapsed .
