Mimas, a moon of Saturn has an orbital radius of #1.87 * 10^8# #m#. What is the orbital period?
The orbital period of Mimas is 0.942 days.
One other piece of information is required to perform the calculation. That is the standard gravitational parameter
Using Kepler's third law which relates the orbital period to the semi-major axis distance
Substituting the values for
This is close to the observed orbital period of Mimas of
