Resumen

We analyze the sample of measured nuclear magnitudes of the observed Jupiter Family comets (taken as those with orbital periods P < 20 years and Tisserand parameters T > 2) to derive sizes of comet nuclei, fraction of active surface areas, as well as to try to gain insight about their physical lifetimes and end states.
