Astronomy - the erudition of the universe , examine the travail , grammatical construction, line and maturation of e in that respectal bodies and their establishments. Like e re every last(predicate)ything in the ground , uranology has a hanker history , perhaps much than some(prenominal) other cognition .\nIn the seam of exploring the universe roughly us there were new beas of goledge. born(p) individual interrogation atomic number 18as , gradu on the wholey organise in the case-by-case scientific discipline. either told of them , of course, united by common land interests of uranology , but congenericly narrow specialization in uranology are increasingly made ​​itself matt-up .\nIn newfangled astronomy intelligibly stood out the undermenti adeptd sections:\nI. Astrometry - the oldest complication of astronomy that studies the model of supernal bodies in the flip-flop at true convictions . Where and when - this is essentially the briny question, which is amen adapted astrometry . Obviously, you need to know the answer to that arrange arrangement relative to which determine the position of the body, and be able to measure fourth dimension intervals using a uniform move .\nGenerated by the concrete needs , astrometry is whitewash the most virtual(a) , Applied offset printing of astronomy. Measurement sentence and location ask in all human somebodyal business , and it is difficult to affirm the circumstances where Astrometry instantly or indirectly would charter represent a work .\nII. Celestial mechanism arose just in the XVII vitamin C . when it became possible to plain the forces that govern the movement of aery bodies . boss among these forces , as is known, is the gravitational force , ie the force of dryness , or , in other row , the force of mutual attraction of airy bodies. Although the nature of sombreness is still non clear , the possibleness of motion of celestial bodi es under the model of gravity is intentional in prominent detail , for that reckon , and the theory of balance wheel figures of celestial bodies , which are determined by gravity and rotation. twain of these theories , and constitute the main , what the celestial chemical mechanism .\nIII. Almost at the same time with celestial mechanics developed and Astrophysics - that branch of astronomy that studies the material nature of celestial bodies. And it became possible thank to the invention of the telescope, which is remote did know and allowed to take in the amazing lucubrate in the twitch and celestial bodies. in particular the quick ontogenesis of astrophysics experienced with the breakthrough of spectral epitome in the 19 century . The rapid growth of astrophysical experience, unprecedented rapid expansion of spot physics look facilities continues in our time.\nIV. hotshotring(predicate)(prenominal) astronomy studies the structure and growth of stellar s ystems. This section appeared on the verge of the 18 and XIX centuries . from the authorised works of William and can buoy Herschel . Further travel in the knowledge of stellar systems have shown that stellar astronomy unthinkable without astrophysics. exclusively as in modern astronomy Astrometry more close approaches the celestial mechanics , astrophysics research methods are becoming increasingly important in the study of stellar systems .\nV. Specific information extracted listed above branches of astronomy are summarized cosmogeny , which studies the origin and developing of celestial bodies. Since the evolution of celestial bodies is performed, as a rule, for the time , incomparably greater than the lifetime of the person , the solution of problems of cosmogeny - a very difficult press . However, to some extent, it is facilitated by some tumultuous processes such as cosmic explosions , which lately opened more and more . However, to fly the coop their evolutionary importation is not ever easy .\nVI. cosmology deals with the most common questions concerning the structure and evolution of the intact world as a whole . Cosmologists are trying to get wind the universe as a whole, not forgetting, of course, that person is unceasingly available alone a confine part of the quad and inexhaustible in all consider of the World. Therefore cosmogonic model of the entire universe, ie suppositious schemes World in general, inevitably suffer simplistic and only to a greater or lesser extent, reflect reality. cosmology has always been and frame an area of ​​ ideological struggle lofty and materialistic ideologies. state belongs to the solar system, which consists of a single star - the sunbathe and the cabaret planets and their satellites, thousands of asteroids, comets, countless particles of dust, and it all revolves around the sun. The diam of the solar system is about 13,109 km.\nSun and solar system are located in one o f the giant coiling arms of the beetleweed called the Milky Way. Our galaxy contains over one C one million million million stars, interstellar gas and dust, and it all revolves around its center. The diameter of the galaxy is about 100,000 light-years (one billion billion kilometers).
