| Abstract: | We present the results of an extensive study of the Tunguska Cosmic Body (TCB) origin on dynamical grounds. To identify the
TCB parent, or a plausible candidate, we applied the well-known concept of dynamical similarity whereby we have compared the
geocentric and heliocentric dynamical parameters of a selected set of the Near Earth Objects (NEOs) and TCB particles. First,
we made use the idea of Kresak by comparing geocentric coordinates of the TCB radiant with those of the NEOs. Second, we studied
the long-term dynamical evolution of all NEOs and TCB particles searching for similarities between their heliocentric orbits.
As a general result, we observed many more similar cases and a different pattern of the high orbital similarity among the
TCB particles and the asteroid orbits than we did for comets. |
