Abstract:

The analysis of application of two dynamical models (``Earth–Moon'' and ``barycentre'' model) in the motion of Near Earth Asteroids was performed. Main aim was the quantitative estimation of the influence of lunar perturbations on the motionof NEA. Additionally, basic tests of application of numerical methods weremade (RMVS3 and B–S methods). The orbits of 1083 Apollo–Aten–Amor and 7 selected AAA objects were adopted as test particles in numerical integration of the motion. The comparison between results obtained by both dynamical models is discussed in detail. In specific cases, the application of the ``Earth–Moon'' dynamical model is very important and cannot be neglected in computations of orbits.
