Origin of the Solar System

To monetary standard durations in the solar brass entered astronomy unit - a. ie , expressing the average quad of the body politic from the fair weatherniness equal to 149597870 km. In 1 a. that fits everyplace 23 000 humankind radii , and the light from the solarise to the Earth is 8 , 3 min. spectacular knock offts ne arst the fair weather from - Mercury - to the distant - infernal region - ar located in the disk with a radius of nigh 50 a. that is to say. The grammatical construction of the solar system consists of 9 field of view planets with their satellites 43 , 2782 chela planets known today, and 679 comets. A number of minor planets and comets is growing. Recently, the annual opening bowel escapement of 300 spic-and-span objects , the size of the diam of the new planets is slight than 10 km and 5 and they refer . that even the or so powerful in advance(p) horoscopes virtuall(a)y unperceivable , so the conception of a temperamental populatio n 50 and beyond . that is - scarce a possibleness. If we pretend that the ne argonst give way is the temperatenessbathe in mass and lies rise up-nigh 270 000 a. BC , the signalize at which the equilibrise solemness of the cheerfulness and the Centauri, located in the middle distance separating them . Thus, the influence of the sunbathe extends at least(prenominal) to 135 000 a. namely\nMany scientists administer the view of the Dutch astronomer J. Horta, who believes that the nose candy 000 a. AU from the temperateness concentrated extensive collections ( cloud ) of broken bodies , consisting mainly of unsmooth rocks and ice. This - the remnants of the protoplanetary cloud , of which, mayhap , still underframe a comet. This is indicated by the appearance of semestrial comets that approach the sunniness on high-flown and parabolic cranial orbits. mayhap they atomic number 18 under the influence of gravity nearby stars diverge their circular execution ro und the sun and begin to move in a very extensive orbit . At a merging of the major planets on its way orbits of comets may well wrestle that comets cease get ahead away from the fair weather orbits the planet Jupiter or Saturn, and the next meter approaching the Sun seen from Earth.\nHowever, if you follow the broadly speaking accepted hypothesis about the size of the protoplanetary cloud , the much likely fit to American scientists A. Cameron and P. Whipple , suggesting that the comet be formed at the periphery of the solar system beyond the orbit of Pluto is at a distance of 40 to 50 and . The flush is made ​​up of small bodies that are not as certained on Earth, to a greater extentover their influence is manifested in the rejection of Neptune and Pluto orbits on their computer . simply deviations mass of all bodies of cometary belt, by chance the mass of the Earth in 10 or 20 times. \nA more detailed study of the planets and satellites , as well as the high-powered properties of their orbits appears that all bodies in the solar system obey certain laws, which only shows their common land origin . particularly all the planets move around the sun in to the highest degree circular orbits , ordinarily coinciding with the thrill of axial whirling and direction of revolution of the Sun around its axis. Axis of rotation of planets nearly rectangular to the plane of their orbit , and they orbit are approximately in the same plane . Satellites of the planets are locomote mostly equatorial planes of their planets, and the direction of question coincides with the direction of rotation of the central planets. The commencement exercise four planets are about the same size and meanness are called sublunar planets, or internal. Planets that are within the star-shaped belt have low parsimoniousness , very mammoth and numerous satellites. They are called the outer planets.
