So it was basic to figure out the masses and such, but I'm not exactly sure what the "orbital separation" really is? Can someone enlighten me? Here is the question for reference:(adsbygoogle = window.adsbygoogle || []).push({});

A moon with a mass one quarter that of its parent planet orbits that

planet with a period of 12 days. The mass of the planet is twice that of

Pluto. What is the mean orbital separation of the planet and its moon?

Thanks for any help.
