Capture D'une COMèTE Par Neptune et Son Passage à L'orbite D'un Satellite de la PLANèTE
Abstract
The classical form of comet capture theory is reviewed, and a new theory is presented that combines it with the theory of comet diffusion, taking into account perturbations due to stars near the almost parabolic orbits of the comets of the Oort Cloud. A fictitious example of the capture of a comet belonging to the Neptune family is given. The following conclusions may be drawn: (1) Neptune, with the cooperation of Saturn and Uranus, determines the evolution of cometary orbits in the solar system; (2) exerting a powerful influence on cometary orbits, Neptune can capture comets and incorporate them into the planetary system, but it can also prevent them from entering this system; (3) the modified theory of comet capture eliminates old discrepancies between theory and observed fact, i.e., all its conclusions are in full agreement with actual orbits and observed comets; and it puts all cometary phenomena in a harmonious ensemble that follows from celestial mechanics and that remains inseparably linked with the powerful planets of the solar system.
