NGC 6028

At a distance of 196 million light years away, NGC 6028 is the nearest (kinematically identified) ring galaxy. It is a "Hoag-type" galaxy that has an intrinsically bright blue ring surrounding a much more yellow/red nuclear region. The space in between seems devoid of much galactic material or certainly star formation. NGC 6028 does, however, put the original Hoag galaxy (PGC 54559) into perspective. Compared to the original, NGC 6028 is not even twice its angular size. However, Hoagʼs galaxy is 3 times more distant. Thus while NGC 6028 is a showy example of ring-like galaxies, the original blossoms to gargantuan scales based on its remoteness.
