SUMMARY
Kepler's Third Law applies to two bodies of different masses, M and m, orbiting their common center of mass in circular orbits. Despite having different masses, both bodies share the same orbital period, which leads to the conclusion that they must have the same radius of orbit around the center of mass. However, this interpretation is valid only when considering the system as a whole; analyzing each body individually does not conform to the traditional Kepler problem. Thus, the law holds true for the entire system rather than for individual bodies.
