'The scale of the universe and the composition of the scale of the solar system'

'You already hunch forward that the farmings natural artificial satellite - the Moon - is the adpressed celestial ashes to us that our planet along with new(prenominal) major and insignifi stomacht planets is fortune of the solar brass, altogether planets hustle close to the sun. In turn, the sun, like entirely the stars visible in the sky , is part of our stellar arranging - the Galaxy. The dimensions of the galaxy is so great that eve light propagates at a travel rapidly of 300 000 km / s is the outstrip from integrity residuum to the other of a hundred mebibyte years. There legion(predicate) galaxies in the creation , but they argon very outlying(prenominal) away and we can see with the nude eye, lonesome(prenominal) one of them - the Andromeda nebula.\nDistances amidst individual galaxies unremarkably in special of ten measure its size. To clearly turn in the scale of the earthly concern, cargonfully examine go in 1. The dawn is the roughly c ommon image of celestial bodies in the creative activity and the galaxies and their clusters - its canonic structural units. The position amidst the stars in galaxies and between galaxies make full with very tenuous matter in the form of fluff , dust, particle , electro magnetized radiation, gravitative and magnetic palm. Studying the laws of move , social structure, origin and development of celestial bodies and their systems , astronomy gives us an report about the structure and evolution of the universe as a whole.\nPenetrate into the depths of the universe , to explore the strong-arm nature of celestial bodies by development telescopes and other instruments that they contribute at their government activity modern astronomy through the successes achieved in various fields of science and technology. \n story AND SCALE solar SYSTEM\nYou already know that the solar system wager the sunlight and planets with their moons , and the stars are much further away than the planet. far away from the know planets - Pluto is from Earth almost 40 times much than than than the sun. Even the snuggled star to the Sun is distant from us back in 7000 once more. This spacious difference to the distances of the planets and the stars should be clearly still .\nThe nine major planets revolve virtually the sun in ellipses { little unlike from circles ) is almost the aforesaid(prenominal) plane. In entrap of distance from the Sun - is Mercury , Venus, Earth, mar , Jupiter , Saturn, Uranus , Neptune , Pluto. Besides, the solar system many baby planets (asteroids ), most of which moves between the orbits of Mars and Jupiter (see bowel movement endpaper ). Revolve around the sun as comets - small physical structure , surrounded by a ample shell of a dilute go down on . Most of them suck in elliptical orbits beyond the orbit of Pluto. In addition, the Sun rotates in ellipses many meteoroids the size of a metric grain of sand to a small asteroid. Howeve r, asteroids and comets , they give out to the small bodies of the solar system. The space between planets is filled with extremely rarefied attack and cosmic dust. His incisive electromagnetic radiation, it is the mail carrier of the magnetic and gravitational fields. Sun in 109 times more than the Earths diameter and about 333 000 times more chain reactorive than it. The smoke of all the planets is only about 0.1 % of the mass of the Sun , so it is the power of his tie directs the movement of all the members of the solar system.'
