The article proposes an approach to the target efficiency estimation for space telescopes of visible range intended for the detection of dangerous celestial bodies (DCB). A comparative analysis of the target efficiency of several variants of such space telescopes placing in the Earth's orbit around the Sun is performed. The most efficient variants of constructing a system of space telescopes were selected among the considered ones with respect to detection of Earth-threatening DCB, unfavorable for observation by ground-based telescopes, during a given warning time. The approach to selecting space telescopes of infrared range rational accommodation is proposed and justification of the choice for determining the physicochemical properties of DCB, unfavorable for observation from the Earth is given.
