Crater counts on Pluto, Charon show small Kuiper Belt objects surprisingly rare

An SwRI-led team studied the craters and geology on Pluto and Charon and found there were fewer small craters than expected. This implies that the Kuiper Belt contains relatively small numbers of objects less than 1 mile in diameter. Imaged by New Horizon’s LORRI camera, the smooth, geologically stable ‘Vulcan Planitia’ on Charon illustrates these findings.

Using New Horizons data from the Pluto-Charon flyby in 2015, a Southwest Research Institute-led team of scientists have indirectly discovered a distinct and surprising lack of very small objects in the Kuiper Belt...
