Abstract
Arguments are presented for a substantial, unexplored population of co mets with radii less than 1 km. Known examples confirm this population and extrapolation of any plausible size-distribution function indicat es large numbers. However, their accurate numbers, orbital characteris tics, and physical properties are unknown. Thus, even though the small comets may be the most frequent cometary bodies impacting the planets , a quantitative evaluation is not currently possible. We advocate an optimized, dedicated search program to characterize this population.
