| Popis: | The Damocloids are a group of unusual asteroids, recently enrolling a new member of 2010 EJ104. The dynamical evolution for the Damocloids may uncover a connection passage from the Main Belt, the Kuiper Belt and the scattered disk beyond. According to our simulations, two regions may be considered as possible origin of the Damocloids: the scattered disk, or a part of Oort cloud which will be perturbed to a transient region locating between 700 AU and 1000 AU. Based on the potential origin, the Damocloids can be classified into two types, with relation to their semi-major axes, and about 65.5% Damocloids is classified into type I which mainly originate from Oort cloud. Whether the Damocloids is inactive nuclei of Halley Family Comets may rely on their origin. Comment: 10 pages, 5 figures, accepted for publication in Research in Astronomy and Astrophysics |
