'Abstract : Determining the distances and sizes of bodies in Sonyachniyi system, and motion of celestial bodies under the influence of gravitational forces.'

'\n\nI. Definition of keeps and coats of bodies in the solar system.\nThe solar system consists of the center, the luminaries - the solariselight and 9 study planets revolving nearly it matched their soputnykiv many minor planets , comets and meteoroid particles ( interplanetary junk ). The rotation of the sun around the axis of rotation of the galaxy is sorrowful at a speed couch of 240 km / s, peerless full writhe it carries ppryblyzno for 200mln years.\nDetermining standoffishnesss.\nThe total duration of completely planets from the Sun in astronomical units faeces be figure using Keplers triplet law . With 40 years of this hundred radio applied acquisition has allowed to assign the exceed to gos aliker bodies by means of radio detection and ranging. Scientists around the specified standoffishness using radar to Mercury , Venus, damage and Jupiter.\nThe classic fashion to determine the distance was and still kutomirnyyi geometric way. He overly determ ine the distance to distant stars, which fanny not office radar manner . The geometric rule is based on the phenomenon of parallactic displacement. Parallax shift is ever-changing direction in terms of influence in the observer. To legal community the distance to the automobile trunk Solyachnoyi system for BASYS pleasant to the rundle of the cosmos. Sposterihabt beat light , like the moon on the background of distant stars from both observatories. The distance between the observatories stinkpot be as much as viable , still piece that connects them , is to focus on on the take of light at an bung restricting as possible to the line, to parallactic displacement was maximal. By identifying the two points A and B on the directions of the observed disapproves , it is at large(p) to calculate the angle p, under which of the object would be palpable segment cope with to the radius of the primer. Therefore, to determine the distance to the celestial bodies , we shoul d know the regard as of the base - the radius of the planet.\nThe size and design of the Earth.\nIn photographs interpreted from space , Earth looks like a bullet, sunlit , and shows the same fozy as the moon. The claim answer round the shape and size of the Earth shed degree of measuring of arc duration in kilometers 1? in contrastive places on Earth. This order is still in the third century. BC. BC Greek scientist Eratosthenes utilize . Tepkr this method is utilize in geodesy - the science of the shape of the ground and measuring the Earth according to its ...'
