Webb25 sep. 2024 · Phobos orbit distance is 9,376 km from Mars; which this makes it the closest satellite to a planet in the Solar System. The moon orbits Mars at 2.138 km/s. Phobos orbit period is 7.7 hours and is below the synchronous orbit radius — which means it moves around Mars faster than the planet moves. 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.
