Assumptions for Jupiter's mass calculation

Asked by InteractiveMind in Math & Science Questions

"Jupiter's moons orbit the planet on circular orbits. The orbital period of Europa is 3.55 days and its semi-major axis is 671,000 km. Using Kepler's 3rd Law estimate Jupiter's mass."

This part is trivial. The question then says:

"What assumption(s) do you have to make?"

This part I'm not so sure on.

I suppose that one assumption I've made, is that the gravitational effects of the other moons can be neglected.
Anything else?
