Contribution

It introduces a simulation of a de-biased NEA population and investigates their close approaches and discovery probabilities.

Findings

Identifies geometrical conditions for close approaches.

Estimates detection probabilities within one year.

Provides a simulated population up to H=28 magnitude.

Abstract

A simulation of de-biased population of NEAs is presented. The numerical integration of modeled orbits reveals geometrical conditions of close approaching NEAs to the Earth. The population with the absolute magnitude up to H=28 is simulated during one year. The probability of possible discoveries of the objects in the Earth vicinity is discussed.
