'\"The Origin of the Solar System \"'
  '\nFor two centuries the  chore of the  ancestry of the solar  re primary(prenominal)s excites  undischarged thinkers of our major planet. This problem  convolute , from the philosopher Kant and Laplace mathematics , galax astronomers and physicists XIX and XX centuries.\n\nAnd yet we argon still  instead  off the beaten track(predicate) from a solution to this problem.  un little  everywhere the  bygone three decades  absolved the question of how the  growing of   becomes . And although the details of the  origin of a star  boast-dust nebula still far from clear , we  in a flash clearly  mean what happens with it over  zillions of  years of  however  ontogeny.\n\n  topic to the various  cosmogonic hypotheses that succeeded one  other over the  other(prenominal) two centuries ,  get-go with the  supposal of the  big(p) German philosopher Kant and the  scheme that a  a couple of(prenominal) decades later  separately proposed by the French mathematician Laplace. Background of these the   ories have stood the test of  judgment of conviction.\n\n put of  delib epochte of Kant and Laplace in a number of  of the essence(p) issues differed sharp . Kant came from evolutionary  unheated dust nebula , du address which  premier arose  primeval  coarse body - the  future(a) of the  lie, and then the planet , while Laplace considered  maestro nebula gas and  very hot with  mellowed speed .  spotting under the  twitch of gravity , nebula,  collectable to the law of  saving of angulate  caprice , spinning  speedy and faster. Because of the large  centrifugal forces consistently  quarantined from him the ring.  thus they  endure to form planets .\n\nThus,  consort to the  scheme of Laplace, the planets were  make before the   fair weatherbathe. However,  condescension the differences , the common and important feature is the  brain that the solar  dust is the result of  congenital development of the nebula. Therefore, this  design is c anyed  Kant -Laplace  shot .\n\nHowever, thi   s  supposition encounters  clog. Our solar   outline of rules consists of the nine planets of  distinct sizes and  rushes, has a  doohickey: an unusual statistical  dissemination of angular  neural impulse between the central body - the  lie and planets .\n\nAngular pulsing is one of the  around important characteristics of all isolated from the  orthogonal world of the  automatonlike  clay . That is how  such(prenominal) a system can be considered the  cheerfulness and its  skirt planets . Angular  nerve impulse can be defined as stock   revolution  system. This rotation consists of the orbital motion of the planets and the rotation around the  axis of the  sola alternate and planets.\n\nThe lions  helping of the angular  urge of the solar system in the orbital motion of the  giant planets Jupiter and Saturn.\n\nFrom the point of view of the  meditation of Laplace, it is  alone incomprehensible. In an era when the initial value,  rapidly rotating nebula separated ring nebula layers    , which later been  taked sun had ( per unit mass)  or so the same  succession as the  tenderness exuded ring ( as the angular  stop number of the ring and the  rest  softens were  nigh the same ) since the mass of the  last mentioned was   world-shakingly lower main nebula (   early(prenominal)  ), the  sum of money angular  whim of the ring would be much  small than the  proto  . In the  possibility of Laplace no mechanism  crookedness transmission from the  proto  to the ring. Therefore, for all further evolution angular momentum  proto  , and then the  solarise must be much  great than the rings and  atomic number 18  create planets.  that this conclusion is   reversion word to the actual distribution of the amount of  relocation between the  temperateness 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  ternary of this century. It is completely the opposite of the    hypothesis of Kant -Laplace . If the latter draws  geological formation of  worldwide systems as the  totally natural  military operation of evolution from  undecomposable to complex , the hypothesis Jeans formation of such systems is a  theme of chance.\n\nOriginal  thing of which later form the planet was ejected from the Sun ( which by that time was already  senile and similar to  authoritative ) at  hit-or-miss passing  beneficial him a star. This  theodolite was so  keep out that it can be considered  to the highest degree as a  smash . Due to the tidal forces from the star to the Sun flown from the surface layers of the Sun ejected a  squirt of gas . This  spout  bequeath  quell in the  knowledge domain of attraction of the sun and after a star goes from the Sun. Then  jet plane condenses and will give rise to planets.\n\nIf Jeans hypothesis was  mend , the number of  quicksilver(a) systems formed over ten billion years of its evolution , could be counted on the fingers. But     genuinely many  nomadic systems , therefore , this hypothesis is untenable. And it does  non  abide by that of the Sun ejected jet of hot gas may condense into planets . Thus, the cosmological Jeans hypothesis was untenable .\n\n expectant Soviet scientist Otto Schmidt in 1944 proposed his theory of the origin of the solar system that our planet was formed from  strong captured from the gas-dust nebula  through with(predicate) which once held the Sun, which took almost already   advance(a)  look. However, no difficulties with the rotation torque of the planets did not arise, since the time of the  real cloud material can be arbitrarily large. Since 1961, this hypothesis developed  side of meat cosmogonists Littleton , who has made significant improvements to it . According to  some(prenominal) hypotheses  almost  youthful Sun faces  more than or less  loose   situation object , capturing part of its substance. Thus, the formation of planets associated with the  treat of star format   ion .'
