Chaotic Properties of Minor Bodies in Retrograde Orbits

Paweł Kankiewicz, Ireneusz Włodarczyk

Small bodies with orbital inclinations above 90 degrees are not compatible with any scenario of evolution in the Solar System. Many clues indicate, however, that they are connected with comets. Currently, more than 100 objects on retrograde orbits are classified as asteroids. In order to determine precisely the dynamic properties of retrograde asteroids, their orbital evolution must be studied, taking into account potential non-gravitational effects. Using various parameters that quantitatively estimate the presence of chaos, it has been possible to determine how long these objects remain inside the system and what factors determine the long-term stability of their orbits.
