R =9400 km , M =6.4*10^23 kg , G =6.67*10^-11 N .m^2/kg^2
From Keplers third law
T^2 = (4pi^2/GM)R^3
T^2 = (4*3.14*3.14*(9400*1000)^3)/(6.67*10^-11*6.4*10^23)
T =27701.2 s
T = 7.695 hours

3. Mars has two moons, Deimos and Phobos, traveling in circular orbits (to a good approximation) Deimos takes 30.3 hours to orbit Mars (i.e. 30.3 hours per full rotation around the planet) and travels with a speed of 1.35 km/s. [16 points] a) What is the radius of Deimos' orbit around Mars? [9] Hint: First find the circumference of Deimos' orbit. Then infer the radius from that.] b) What is the magnitude and direction of Deimos' acceleration? [7]

Phobos is one of two small moons that orbit Mars. Phobos is a very small moon and has correspondingly small gravity-- it varies but a typical value is about 6mm/s^2. Phobos isn't quite round, but it has an average radius of about 11 km. What would be the orbital speed around Phobos, assuming it was round with gravity and radius as noted?

A satellite of Mars, called Phobos, has an orbital radius of 9.4 ✕ 106 m and a period of 2.8 ✕ 104 s. Assuming the orbit is circular, determine the mass of Mars.

There is a planet with two moons, Moon D and Moon P. Moon A is located in a stable circular orbit 2398 km from the surface of the planet, has an orbital period of 19 hours, and was a magnificent moon which served as the intellectual center of the whole sector. The other moon - Moon B - is a considerably smaller body. Moon D is in a stable circular orbit 59850 km from the surface of the planet and...

An undiscovered planet, many light-years from Earth, has one moon, which has a nearly circular periodic orbit. If the distance from the center of the moon to the surface of the planet is 2.015 ~ 10 km and the planet has a radius of 3475 km and a mass of 4.00 x 1022 kg, how long (in days) does it take the moon to make one revolution around the planet? The gravitational constant is 6.67 x 10-11N.m²/kg?. T = days
