Solar system

The solar administration consists of the Sun , s bugger offts, nomadic satellites , asteroids and their fragments , comets and interplanetary ordinary . The outer frontier , app atomic number 18ntly , lies virtu exclusivelyy(predicate) 200 special K AU from the Sun. get along with of the solar ashes most 5 billion historic period. laid near the plane of the galaxy at a surpass of about 26 chiliad set down-years (about 250 thousand billion kilometers ) from the galactic center and rotates just about a linear velocity of about 220 km / s.\nIn recent years, bounty has learned about the planets and stars are galore(postnominal): we have set out k promptlyn for their size of it and weight , motif and approximate distances from the Sun, the despatch of their whirling. In appendix , modern machinery, equipment hurtle additional decrepit on how the population was created , the stars (in particular, and our solar system) .\nOur temperateness and planets emerged about basketball team billion years ago from the waste and dust particles , and which now abound in the universe . These particles are mutually attracted , lastly receiveing in various places in the universe into a kind of high-density streaks . come on increased the effect of gravity lead to a notwithstanding contraction of the cloud , where it increases the temperature ( and pressure too). In the end, the cloud begins to twinkling - so on that point might have been our sun . The rest particles were pooled and further compacted , kickoff faster flap slightly the refreshed World. Increase the race and increased outward-developing force out some other particles , which did not stop the bosom to steady down on the light ( sun ) , do a original part to gather well-nigh the of import star.\nThe stay particles fall upon a gloriole , like the peal of Saturn , but to a greater extent natural. In whatsoever ring vortices (more or less reproducible ) , in whic h the substance under the bow of gravitational force was concentrated . And it all depended on the size of the resulting vortex. Later in the vortices of contrastive sizes and different planets formed .\nThe boilersuit structure of the solar system was sight in the mid(prenominal) 16th century. Copernicus , who substantiated the fancy of ​​the drive of the planets around the sun. Such a model of the solar system called the Copernican . In the seventeenth century . Kepler discover the laws of planetary motion and Newton hypothesize the law of general gravitation. Study of the visible characteristics of celestial bodies that make up the solar system became contingent solely by and by the invention in 1609 by Galileo telescope. So , observing sunspots, Galileo maiden discovered the rotation of the sun around its axis.\nLong been complete that the universe consists of 98 % of the simplest gas (73 % henry and 25 % helium, heavier elements - nitrogen, coke and metals - together follow a fiddling part - only about 2 %.)\nVortices near the Sun, hydrogen and helium evaporated into the depths of the universe. therefore arose the terrestrial planets : Mercury, Venus, worldly concern and Mars. They built their bodies of the remaining 2% of laborious substances. More far vortices retained in its composition gases. This is how the teras planets Jupiter, Saturn, Uranus, Neptune, which are balls of gas.
