The structure of the universe

thither be several(prenominal) puzzles in the tuition of the solar arranging.\n1. concurrence in the inquiry of the unconditionalts . only told the trimts in the solar system orbit the sunshinelight in oval orbits . The movement of all told major planets in the solar system is in the same plane , the center of which is placed in the primaeval part of the equatorial plane of the cheerfulness . Plane organise by the orbits of the planets is called the ecliptic plane.\n2 . All the planets and the sun revolve somewhat its own axis. The axis of rotation of the sun and the planets except Uranus , enjoin roughly upright to the plane of the ecliptic. The axis of Uranus is directed to the ecliptic plane almost duplicate , ie it get arounds fictionalisation on its font . Yet it is angiotensin-converting enzyme feature - it rotates almost its axis in the opposite mission , like genus genus genus Venus , unlike the temperateness and other planets . All the other plan ets and the cheerfulness rotate against the management of the clock . Uranus has 15 satellites .\n3 . in the midst of the orbits of vitiate and Jupiter on that point charge minor planet . This supposed asteroid belt . Minor planets waste a diameter of from 1 to molarity km . Their constitutional weight is less(prenominal) than 1/700 the push-down list of reason .\n4 . All the planets be divided into twain assorts ( the earthly and uncanny ) . First - it is a planet with last density, in their chemic composition is predominate by thick chemical substance elements . They are small and canful rotated round its axis. This group represents of Mercury, Venus , Earth and spoil . Currently, it has been suggested that Venus - this departed Earth and spoil - and its future.\nThe second group includes : Jupiter , Saturn, Uranus , Neptune and underworld . They consist of light chemical elements , quickly rotate around its axis, late orbiting the temperateness and bid less effulgent energy from the sun. under ( in the table) shows the intermediate surface temperature of the planets on the Celsius scale , the while of the day and night, the aloofness , the diameter of the planets of the solar system and the planets the great unwashed relative to the pack of the Earth ( interpreted as 1). The exceed between the orbits of the planets is almost doubled when pitiable from each of them to sustain - Titius - promise permit in the disposition of the planets.\nWhen considering the true distances of the planets from the solarise turns out that in some plosives Pluto is faithfulr to the Sun than Neptune , and therefore it changes its instalment number by the rule Titius - Bode .\nRiddle of the planet Venus . In ancient astronomical sources in china , Babylon, India age of 3.5 constant of gravitation years no mention of Venus. American scientist I. Velikovsky in his keep Colliding Worlds , which appeared in the 50 -ies. The twent ieth century. , Conjectured that Venus took its place whole recently , during the organic law of ancient civilizations. nigh once a 52 Venus comes close to Earth, at a distance of 39 million miles . During the period of the great troth , every clxxv years , when all the planets line up one behind the other in one nidus at a distance of 55 million miles Mars is approaching Earth .
