Abstract

The paper deals with the investigation of regular and chaotic dynamics of near-Earth asteroids (NEAs) in the vicinity of resonance 1:1 with Venus. The degree of chaoticity of NEA orbits is determined by analyzing the behavior of parameters MEGNO and OMEGNO. It is shown that the asteroid motion in the resonance vicinity and/or multiple close approaches of NEAs with planets lead to the appearance of dynamical chaoticity.
