We identify a sample of 27 long-period comets for which both non-gravitational accelerations and Lyman- α based gas production rates are available. Seven of the 27 comets (i.e. ∼ 25%) did not survive perihelion because of nucleus fragmentation or complete disintegration. Empirically, the latter nuclei have the smallest gas production rates and the largest non-gravitational accelerations, which are both indicators of small size. Specifically, the disintegrating nuclei have a median radius of only…
