Two identical probes are sent along the same path toward a neutron star. A neutron star is very dense, packing as much as 2 solar masses into a sphere with a radius on the order of 10 km. At the moment shown, the two probes are 46.5 km and 193 km away from the center of the neutron star, respectively. Find the distance between the center of mass of the two probe system and its center of gravity.
