• Density of asteroids (2012, background): “The resulting macroporosity is generally high ( P Z 30 (cid:2) 50 % ), consistent with our current understanding of the structure of a comet nucleus: a highly porous assemblage of ices and silicates (see, Weissman et al., 2004, for a review).”
• A ballistics analysis of the Deep Impact ejecta plume: Determining Comet Tempel 1's gravity, mass, and density (2007, methodology): “…the agreement of our results with these previous estimates is good, all of these estimates are based on the computation of non-gravitational forces for the various cometary nuclei, computations that involve many assumptions and are generally regarded as very uncertain (Weissman et al., 2004).”
