This value, together with the 2008 TC3 asteroid shape model and albedo, was used to estimate the asteroid\u2019s mass. Based on the study of recovered meteorites and the atmospheric entry observations the asteroid 2008 TC3 is compositionally heterogeneous and of low mechanical strength. Thus we consider the presence of significant macroporosity likely, lowering asteroid\u2019s bulk density compared to that of the Almahata Sitta ureilites. Most realistic albedos lie in a range of 0.09 0.2 and the presence of significant macroporosity leads to mass estimates below 20 x 103 kg, which is lower than previously estimated. The presence of a non ureilitic fraction and space weathering may affect the albedo and also influence the mass estimates. However, from current data it is not possible to quantify this effect."@en . . "Scheirich, Peter" . "0019-1035" . . "RIV/67985831:_____/11:00367277" .
