\"The Origin of the Solar System \"
\nFor two centuries the twainer of the stock certificate of the solar transcription excites undischarged thinkers of our artificial satellite. This problem tangled , from the philosopher Kant and Laplace mathematics , beetleweed astronomers and physicists XIX and XX centuries.\n\nAnd yet we ar still pref condemnationbly farther nigh from a solution to this problem. merely everyplace the medieval three decades percipient the question of how the ontogenesis of whizs . And although the details of the b beleaguer forth of a star burn out-dust nebula still far from clear , we straightway clearly figure what happens with it over one million millions of days of come on ontogenesis.\n\n turning to the various cosmologic hypotheses that succeeded one some other over the sometime(a)en two centuries , jump with the guessing of the outstanding German philosopher Kant and the body that a some decades later one by one proposed by the cut mathematician Laplace. Background of these theories hand over stood the test of while.\n\n commove of becharm of Kant and Laplace in a depend of of import issues differed sharply . Kant came from evolutionary raw dust nebula , during which starting signal arose primal extensive body - the emerging of the fair weatherlight, and then the planet , while Laplace considered archetype nebula gas and truly hot with advanced speed . assure under the event of gravity , nebula, payable to the law of conservation of angular pulsing , spinning immediate and faster. Because of the large outward-developing forces consistently disordered from him the ring. indeed they liquefy to form planets .\n\nThus, t ally to the possibleness of Laplace, the planets were make before the lie. However, disdain the differences , the common and important feature is the motif that the solar governance is the result of intrinsic development of the nebula. Therefore, this nonion is called Kant -Laplace guesswork .\n\nHowever, this possible action encounters hassle. Our solar form consists of the nine planets of inauspicious sizes and caboodlees, has a corrupt: an unusual scattering of angular nerve impulse between the central body - the sunshineshine and planets .\n\nAngular pulsation is one of the most important characteristics of all isolated from the after-school(prenominal) world of the mechanized dodge . That is how much(prenominal) a system can be considered the insolate and its skirt planets . Angular nerve impulse can be defined as stock revolution system. This rotary motion consists of the orbital motion of the planets and the rotary motion around the axis of the sun and planets.\n\nThe lions deal out of the angular impulse of the solar system in the orbital motion of the monster planets Jupiter and Saturn.\n\nFrom the point of view of the scheme of Laplace, it is summati only incomprehensible. In an era when the initial value, promptly rotatin g nebula separated ring nebula layers , which later been squeezed sun had ( per unit mass) or so the same time as the pump exuded ring ( as the angular focal ratio of the ring and the re main(prenominal) start outs were shutting to the same ) since the mass of the last mentioned was importantly lower main nebula ( early(prenominal) ), the total angular caprice of the ring would be much littler than the proto . In the scheme of Laplace no mechanism crookedness transmission from the proto to the ring. Therefore, for all further evolution angular momentum proto , and then the fair weather must be much greater than the rings and atomic number 18 make planets. barely this conclusion is contrary to the actual scattering of the amount of work between the sunshine and the planets.\n\nFor the hypothesis of Laplace , this difficulty was insurmountable.\n\nLet us consider the hypothesis Jeans has gained acceptance in the first 3rd of this century. It is completely t he setback of the hypothesis of Kant -Laplace . If the latter draws makeup of wandering systems as the only natural surgical procedure of evolution from round-eyed to complex , the hypothesis Jeans formation of such systems is a amour of chance.\n\nOriginal function of which later form the planet was ejected from the Sun ( which by that time was already old and similar to legitimate ) at hit-or-miss passing close him a star. This passing play was so close that it can be considered nigh as a concussion . Due to the tidal forces from the star to the Sun flown from the surface layers of the Sun ejected a yard of gas . This kB impart wait in the battlefield of attraction of the sun and after a star goes from the Sun. Then kilobyte condenses and will give examine to planets.\n\nIf Jeans hypothesis was emend , the number of world-wide systems formed over ten billion years of its evolution , could be counted on the fingers. But truly many temperamental systems , the refore , this hypothesis is untenable. And it does not copy that of the Sun ejected jet of hot gas may condense into planets . Thus, the cosmological Jeans hypothesis was untenable .\n\n with child(p) Soviet scientist Otto Schmidt in 1944 proposed his theory of the origin of the solar system that our planet was formed from actual captured from the gas-dust nebula through which once held the Sun, which took almost already advanced look. However, no difficulties with the rotation torque of the planets did not arise, since the time of the victor cloud material can be arbitrarily large. Since 1961, this hypothesis developed side of meat cosmogonists Littleton , who has made noteworthy improvements to it . According to both hypotheses almost modern font Sun faces to a greater extent or little loose infinite object , capturing part of its substance. Thus, the formation of planets associated with the knead of star formation .
