The method used to determine the mass/density of Tempel 1 was very iffy; essentially they measured the trajectory of particles ejected by the impact. However, since the observing probe closed its eyes shortly after impact, there is uncertainty in the amount of time ejecta was being lifted from the surface.

We will have to set up a pool on this...
