Degree of implementation: development is implemented at all stages of the work. Scope: Observatories that study near-space objects and prevent hazardous asteroids to Earth. Solving the problem of asteroid-comet danger requires knowledge of the physicochemical characteristics of potentially dangerous objects. The report describes astronomical complexes of the Observatory at Peak Terskol . In order to supplement the physical characteristics of small bodies of the Solar system, observations of selected asteroids were performed on a regular basis. The world achieves a high level of precision for positional observations of weak objects. Keywords: asteroids, positional observations, photometry of celestial bodies, asteroid-comet danger.
