Abstract:

Asteroids on retrograde orbits (i > 90рю) are known since 1999. Some of them are Centaurs, small Transneptunian bodies, or potential comet nuclei. Their possible origin is still not explained in detail. They can be transported into the inner part of Solar System by perturbations, especially secular resonances with outer planets. Such scenarios are shown in the presented work.

Key words:
