The following questions relate to other Moons in our solar system.
a. Europa is a Galilean satellite of Jupiter, where there is most probably a liquid water ocean underneath a thick cover of ice due to internal heating caused by the interaction with Jupiter and the other Galilean moons . The orbital period of Europa is P = 3.551 days; the semimajor axis of its orbit is a = 670 900km. Given this information, find the mass of Jupiter.
b. Deimos is the outer moon of Mars. The orbital period of Deimos is P = 1.263 days; the semimajor axis of its orbit is a = 23 463.2km. Find the mass of Mars.
