Phobos shape
Webb10 dec. 2024 · We note that, even with a numerical shape model, determining the local gravity direction is not simple due to the Phobos’ proximity to Mars. Nevertheless, we can calculate the gravity field with a constant density value for Phobos’ entire body to evaluate the local gravitational acceleration in every facet (i.e., the face that constitutes the … Webb4 okt. 2024 · Phobos has an oblong shape with an average diameter of about 14 miles (22 kilometers).
