One of Saturn's moons has an orbital distance of 1.87× 10m to the 8 power. The mean orbital period of this moon is approximately 23 hours. Use this information to estimate a mass for the planet Saturn.

Answer 1

force gravity=force centripetal
GMm/orbitdistance^2=mv^2/orbitaldistance
,,notice m, the mass of the moon divides out...
but v=2PIorbitaldistance/Period

put thatin for v, and then solve for the mass of Saturn M
