Abstract: The study continues our previous publications on searching for the main source of nuclei of Jupiter family comets (JFCs). We analyze the distributions with the angular orbit elements of comets and asteroids from different groups. The distributions of JFCs with argument of perihelion ω and with longitude of perihelion π are studied. It is revealed that these distributions were not formed during the evolution of JFCs on their current orbits. The bodies that passed into JFC orbits from external sources have not N(ω) and N(π) distributions of these kinds. At the same time, the distributions of JFCs with all angular elements are very close to the corresponding distributions of Trojans. The conclusion is made that asteroids of just that group is likely the main source of JFCs nuclei. |
