Circular motion of identical spheres in space

  1. Sep 22, 2008 #1
    Hey everyone,
    I have this question that does not make much sens to me and I can't find any clue on the internet.

    Find the shortest possible periode of revolution of two identical gratitating solid spheres which are in circular orbit in free space about a point midway between them. (You can imagine the spheres fabricated from any material obtained by man.)

    Some help would be appreciated.
    have a good day

    I think Newton's version of Kepler's 3rd law would be appropriate for this problem.
