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 com-

parative 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 tele-

scopes of infrared range rational accommodation is proposed and justification of the

choice for determining the physicochemical properties of DCB, unfavorable for observa-

tion from the Earth is given.

Keywords:

asteroid-comet danger, visible range, infrared range, space telescope, dan-

gerous celestial bodies, target efficiency
