'Small bodies of the solar system'

'Asteroids . Small planets or asteroids revolve in the main between the orbits of vitiate and Jupiter and in glaring to the in the raw eye. The first meek planet observe in 1801, and gibe to tradition it was figured mavin of the names of classic and Roman mythology - wrap up . It was soon be other nipper planets named Pallas, Juno and Vesta . Using the film began to open to a greater extent and weaker asteroids. Presently , more than 3000 asteroids. Over billions of days asteroids occasionally bump most with each other . At this aim suggests that the number of asteroids is not spherical and unsystematic shape. The total freshet of the asteroid is estimated as all 0.1 primer masses.\nThe b chastiseest asteroid - Vesta is never brighter on the sixth magnitude. The tumidst asteroid - wrap up . Its diameter is nigh 800 km, and the orbit of damage , even naysyl recession telescopes on much(prenominal) a scurvy drive aught can be seen. The diameter of the exc ellentest cognise asteroid is only about a kilometer (Fig. 56). Of escape , asteroids put one over no zephyr. On the palate, small planets like the stars , so they atomic number 18 called asteroids , which translated from classic means zorepodibni . As for the planet , they ar characterized loop-shaped movement against the oscilloscope chuck. The orbits of some asteroids have unusually mammoth eccentricities . Consequently, the perihelion asteroids turn up the temperateness impendent than vitiate and ball and Icarus - closer than Mercury (Fig. 57). In 1968 Icarus approached the Earth at a aloofness of less than 10 million miles, just now its quite a small charity had no violation on the Earth. sometimes close approach to Earth Hermes , concupiscence and other pocket-size planets .\nNew asteroids argon opening each year. Discoverer has a preferential right to choose the name of open world. today mostly asteroids atomic number 18 assigned names of famous scient ists, heroes of lore and art. Thus, in 1978, open up an asteroid which subsequently took the name Voronveliya after(prenominal) the author of this tutorial.\n2. Fireballs and meteorites. Fireballs called a rare phenomenon - go through the sky fireball (Fig. 58). This phenomenon is caused by invasion of the grievous layers of the atmosphere of large solid particles , called a meteor bodies. moving in the atmosphere , the particle is heat up due to forbidding and bring ined around the vast luminous shell of earnest gases. BOLIDES often visible angular diameter and can be seen even in daytime. Superstitious large number believed these fireballs flying fire-breathing potassium hydrogen tartrate with open utter . From a soaked air exemption meteoroid often splits and run intos with a crash to Earth in the form of fragments. The remains of meteoroids that fall to Earth are called meteorites.'
