Why planets in solar system orbit in circular path ?
Palu – the planets actually rotate in an elliptical path around the sun (and the moons do the same around their planets). It is best described by the Laws of Planetary Motion, Kepler obtained Brahe’s data after his death despite the attempts by Brahe’s family to keep the data from him in the hope of monetary gain. There is some evidence that Kepler obtained the data by less than legal means; it is fortunate for the development of modern astronomy that he was successful. Utilizing the voluminous and precise data of Brahe, Kepler was eventually able to build on the realization that the orbits of the planets were ellipses to formulate his Three Laws of Planetary Motion. Kepler’s First Law: I. The orbits of the planets are ellipses, with the Sun at one focus of the ellipse. The Sun is not at the center of the ellipse, but is instead at one focus (generally there is nothing at the other focus of the ellipse). The planet then follows the ellipse in its orbit, which means that the Earth-Sun d
