How fast does Phobos orbit Mars?

every 7 hours 39 minutes
Phobos has an equatorial orbit, which is almost circular. It orbits once every 7 hours 39 minutes just 5989 km above the surface of Mars. Its orbit is decaying by 1.8 cm per year, so it is expected to crash into Mars, or break up to leave a ring of fragments around the planet, within 100 million years.
