Orbital structure of the Kuiper belt and its contribution in the near-Earth asteroid and meteor population

Numerical calculations are given to describe evolution of orbits of simulated and real Kuiper belt objects for large intervals of time. Gravitational perturbations caused by all major planets have been taken into account, and, when considering small particles, Poynting-Robertson nongravitational effect has also been incorporated. Large orbit scattering of the Kuiper belt objects regarding the semimajor axes and eccentricities is shown to be due to their evolution over millions of years. Relative contribution of great objects and meteor particles from the Kuiper belt into the near-Earth population is believed to be extremely small.
