The findings suggest a common source of water for both objects. This supports a theory that Jupiter temporarily migrated into the inner Solar System, destabilizing the orbits of water-rich carbonaceous chondrites. As a result, some of the bodies could have fallen inwards and become part of the raw material for making Earth and its neighbors.[7] The discovery of water vapor out-gassing from Ceres provides related information on water-ice content of the asteroid belt.[8]
