Abstract

An approach is proposed for constructing celestial maps of the distribution of the probabilities of the appearance and detection of near-Earth objects (NEOs), including objects potentially dangerous for Earth inhabitants. The proposed model will take into account the distribution of NEOs over mass and orbital elements obtained after the observational selection. The results of calculations of the migration of bodies from various regions of the solar system to the Earth's orbit will be used for construction of the distributions of the incoming bodies over their orbital elements. The construction of sky brightness models for telescopes used in observations is discussed, and the approaches for comparison of NEOs search efficiency by different telescopes (including the ISON-NM and ISON-SSO telescopes and projected space telescopes) are considered. The proposed models will allow observers to understand to which regions of the sky it is needed to pay more attention during observations. The comparison of the distribution of the discovered NEOs by their orbital elements corrected by taking into account the observational selection with similar distributions of bodies coming from different regions of the solar system will allow one to evaluate the role of different NEOs replenishment sources (asteroids, comets, trans-Neptunian objects) for various orbital elements of NEOs and for various observational regions. This comparison will allow one to better understand the typical composition of NEOs in different orbits.

Keywords:

near-Earth objects, probabilities of detection, observational selection, migration of bodies, sky brightness model, telescope, search efficiency
