WebAssuming Phobos is made of a mixture of poros- ity (macro-porosity or micro-porosity), Rosenblatt et al. (2011) have proposed models of heterogeneous internal mass distribu- tion inside Phobos, which can fit its bulk density and librational angle. Numerical models suggest that the formation of Stickney Table 1. WebPhobos is the larger of the two moons, and is the closer of the two to Mars. Phobos has an average radius of 11 km, while Deimos has an average radius of 6 km. The origin of Mars' moons, Phobos and Deimos (pictured right), is unknown and remains controversial. One theory is that the moons are captured asteroids.

Webcorresponding range of the body’s porosity (30% ± 5%), provide a basis for improved interpretation of the internal structure. We conclude that the interior of Phobos likely contains large voids. When applied to various hypotheses bearing on the origin of Phobos, these results are inconsistent with the proposition that Phobos is a captured ... my family season 8

WebMay 7, 2010 · The porosity of Phobos is computed from its mass, its bulk density and known grain densities of the hydrous chondrites of the CM group and the Tagish-Lake meteorite … Webof Phobos to be 1.87 g cm 3 with a porosity of 25–35% (Andert et al., 2010; Pätzold et al., 2014; Rosenblatt et al., 2010) – such low density and high porosity are uncommon for most asteroids. An asteroid with such a composition would not be expected to remain coherent if it was dynamically captured (Craddock, 1994), WebThe polar body, with haploid DNA, is a small cell produced during the meiosis of an oocyte.
