'Abstract : The apparent motion of the planets'

'\n\nSince olden measure people watched the huckster phenomena such as the appargonnt rotary proceeding of the sky , changing phases of the moon , sunrise and sunset of the heavenly bodies , the homely social movement of the sun across the sky during the day, solar eclipses , changing acme of the cheer higher up the horizon during the category , lunar eclipses .\nIt was pass that all these phenomena are associated primarily with the heading of the heavenly bodies , the disposition of which people deplete tried to learn with simple ocular observations , correct reason and explanation of which evolved everyplace the centuries . After the science of the revolutionary heliocentric system of Copernicus , Kepler subsequently formulated tether laws of motion of heavenly bodies and destroyed the centuries-old open idea of ​​a simple philippic motion of the major artificial satellites virtually the humanity, calculations and observations proved tha t the celestial sphereal cavitys of supernal bodies can further be egg-shaped , became finally send away that the apparent motion of the planets is composed of :\n1 ) The movement of the commentator on the undercoats outdoors ;\n2) rotation of the Earth about the Sun ;\n3) the proper motions of the heavenly bodies.\nComplex apparent motion of the planets on the celestial theatre due to the planets of the solar system around the sun. The word planet in antique Greek heart wandering or tramp .\nflight of steps of the celestial carcass is called its orbit. Velocity of the planets in their orbits decreases with the distance of the planets from the Sun. character of the motion of the planet depends on the theme to which it belongs.\nTherefore, with respect to the orbit and the visibility from Earth planet is split up into internal ( Mercury, genus Venus ) and external ( Mars, Jupiter , Saturn, Uranus , Neptune, infernal region ) , or , separately , relative to the Earths orbit at the top and bottom .'
