**Abstract:**

Currently, ‘central force’ – an apparent effort between two free macro bodies along the line joining them – is estimated in relative frames of reference. It is also assumed that action by ‘central force’ directly corresponds to its magnitude. Estimation of magnitude and direction of ‘central force’ on planetary bodies or central body, in a planetary system, assumes that the centre of planetary system is static in space. While considering a satellite’s orbital path, centre of corresponding planet is assumed static in space. Although such calculations help to determine relative positions of these macro bodies, it obscures causes and magnitudes of many other important phenomena, related to planetary motion. Determining magnitude and direction of ‘central force’ and its action with respect to absolute reference can give us logical explanations to many puzzling phenomena on planetary motions/systems.
