WebFeb 1, 2014 · The second degree gravity field of Phobos ( C 20, C 22) could not be solved for at sufficient accuracy. The low bulk density suggests a high porosity and an inhomogeneous mass distribution but the large errors of C 20 and C 22 are still consistent with a homogeneous as well as an inhomogeneous mass distribution. WebPhobos has dimensions of 27 km x 22 km x 118 km, and retains too little mass to be rounded under its own gravity. Phobos does not have an atmosphere due to its low mass and low gravity. It is one of the least reflective bodies … WebNov 4, 2024 · Phobos, the 22 km diameter innermost moon of Mars, orbits only 6000 km above the planet and is gradually spiraling in as a result of tides. Unlike Deimos, half its size and much farther from Mars, Phobos has developed a striking pattern of parallel linear features running over its surface (Thomas et al. 1979).These "grooves," typically 100–200 … morphen powerpoint 2010
