Some aspects of the distribution of asteroids in the near-Earth space

To create an efficient NEO observation system one need to know distribution of close encounters with NEOs on the celestial sphere. This paper is dedicated to study a distribution of NEO close approaches (0.01 AU) to Earth, averaged by directions on the celestial sphere over a long time interval. A numerical simulation of evolution of the NEO population is used. It is shown that flux of NEOs is nearly isotropic. Results obtained may be useful for estimates of efficiency for telescopes used for searching a night-time and day-time potentially hazardous bodies.
