Surface evolution from orbital decay on Phobos and Triton

WebbPhobos is steadily spiraling inward due to the tides it raises, and will suffer tidal disruption before colliding with Mars. We calculate the surface stress field of the de-orbiting satellite and show that the first signs of tidal disruption are already present on its surface. WebbPhobos is roughly 22 km in diameter and orbits closer to Mars, with a semimajor axis of 9,377 km. Deimos is smaller—roughly 12 km in diameter—and orbits farther from Mars, with a semimajor axis of 23,460 km. The orbital periods of the two moons ar... how to show triggers in portal 2WebbDeimos. Phobos, the larger of the two moons, is orbiting with a mean distance of 9375 km to the center of Mars, deep in the gravitational ﬁeld of the planet.
