| Summary: | The paper presents the results of investigation of dynamical behaviour of known SOHO comets, assuming their orbits to be near-parabolic. Their parabolic orbits derived from the coronographs data covering short near perihelion part of the orbits are not precisely determined and it is possible to make assumption about their near parabolic eccentricities. Sungrazing comets discovered from the Earth with better determined orbits support this idea, too. The long-term numerical integrations of the model SOHO comets with the near parabolic eccentricities show periodical changes of their eccentricities, inclinations and perihelion distances. Majority of their revolution around the Sun pass within the space behind the Mars orbit. Some of these bodies come periodically to the vicinity of the inner planets. |
