To understand the gravity of Mars, its gravitational field strength g and gravitational potential U are often measured. Simply, if Mars is assumed to be a static perfectly spherical body of radius R M, provided that there is only one satellite revolving around Mars in a circular orbit and such gravitation interaction is the only force acting in the system, the equation would be,

D. 2.4 104 s The moon Deimos orbits the planet Mars at an orbital radius of 2.34 107 m with an orbital period of 1.08 105s. What is the mass of Mars? A satellite orbits the Earth with a speed of 5.2 103 m/s. What is the satellite’s distance from the centre of the Earth?
