Physical characteristics
PGC 1 appears to have a companion galaxy called SDSS J235958.29+004208.6. 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 Jet
PGC 1 has a radio jet coming out of its center.[4]
