However, the difference in the recessional velocities for the two galaxies corresponds to about 55 million light years difference in distance, so it is possible that they may not be a physical pair, but however they are essentially the same distance.[3] Radio JetPGC 1 has a radio jet coming out of its center.[4] See also
