4. Assuming that Phobos moves around Mars on a perfectly circular orbit in the equatorial plane of the planet, give the length of time Phobos is above the horizon for a point on the Martian equator. Use the following data:

Radius of Mars $R_{\mathrm{Mars}}$ = 3 393 km Rotational period of Mars $T_{\mathrm{Mars}}$ = 24.623 h. Mass of Mars $M_{\mathrm{Mars}}$ = 6.421 × 10$^{23}$ kg Orbital radius of Phobos $R_P$ = 9 380 km .
