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 has two particularly striking geologic features: first is the crater Stickney, which dominates the Mars-facing hemisphere. Jennifer A. Grier, Andrew S.
