1110.3964 (D. Farnocchia et al.)

For how long is a NEO survey blind with respect to small impactors?    [PDF]

D. Farnocchia, F. Bernardi, G. B. Valsecchi
In the framework of the European Space Situational Awareness program, we considered a network of telescopes capable of scanning all the observable sky each night, in order to determine the efficiency of discovering Near-Earth objects (NEOs) in the size range of the Tunguska-like asteroids, from 160 m down to 10 m. In the present paper we measure the performances of the proposed survey in terms of the time needed to discover with a reasonable advance at least 50% of the impactors in the considered population. Our results suggest that the studied survey would be a significant addition to the current NEO discovery efforts.
