WebPhobos, a moon of Mars, has an orbital period of 7.7 hours and an orbital radius of 9.4x10^3km. Outline why Phobos moves with uniform circular motion. The gravitational force of Mars provides a centripetal force towards the centre of Mars. Because the radius is constant, there is a constant centripetal force at 90° to the direction of the velocity. Phobos orbits 6,000 km (3,700 mi) from the Martian surface, closer to its primary body than any other known planetary moon. It is so close that it orbits Mars much faster than Mars rotates, and completes an orbit in just 7 hours and 39 minutes.
