This structure, known as Stickney, measures about 10 km (6 miles) across. Precise observations of Phobos’s position over the past century suggest that tidal forces from Mars are slowly pulling the satellite toward the planet. If such is the case, it will collide with Mars in the very distant…

The largest, the crater Stickney, is about half as wide as the satellite itself. Its surface also exhibits a widespread system of linear fractures, or grooves, many of which are geometrically related to Stickney. In contrast, the surface of Deimos appears smooth, as its many craters are almost completely…
