Planetary orbits

An orbit is the gravitationally curved (regularly repeating) imaginary trajectory of an object around another body. The central body is always assumed static in space and the orbiting body is assumed to move around the central body. Except for gravitational attraction, all macro bodies in space are independent of each other. Those bodies in a group that are relatively nearby and having considerable gravitational attraction between them are considered as a planetary system. All macro bodies in a planetary system arrive from outside the system. All objects in nature move at great linear speeds. It is physically impossible for a free macro body to orbit around another moving body in any type of geometrically closed path. Hence, real planetary orbits are not around their central bodies but are wavy about the mean paths of central bodies, alternatively moving in front and rear of the central body under mutual gravitational attraction. Eccentricity and curvature of segments of these paths on either side of mean path of central body are determined by their relative parameters. Central bodies of planetary systems orbit around respective galactic centers. Therefore, planetary orbits about a corresponding central body are ideally in the plane of central body’s orbital path around galactic center. Minor discrepancies are removed in due course of time.
