NGC 6028 is a barred [3] lenticular galaxy [4] and a ring galaxy [3] located about 200 million light-years away [4] in the constellation Hercules. [5] Ring galaxies such as NGC 6028 are also known as Hoag-type galaxies as they may have a resemblance to the prototype, Hoag's Object. [3] NGC 6028 was discovered by astronomer William Herschel on March 14, 1784. It was then rediscovered by astronomer Guillaume Bigourdan on May 4, 1886. [6]

Physical characteristics

NGC 6028 consists of a luminous core that is surrounded by a fainter outer ring. Unlike Hoag's Object, NGC 6028's core is elongated indicating the presence of a weak bar embedded in a lens-like structure. The outer ring of the galaxy appears asymmetric in structure and may be made up of tightly wound spiral arms. The observed asymmetry could be the result of one arm being richer in H II regions than the other arm. [3]

Group membership

NGC 6028 appears to lie near the Hercules cluster in the sky. However, NGC 6028 is not a member of that cluster but instead belongs to a foreground group of galaxies known as G47. [3]

<span class="mw-page-title-main">NGC 4762</span> Lenticular galaxy in the constellation Virgo

NGC 4762 is an edge-on lenticular galaxy in the constellation Virgo. It is at a distance of 60 million light years and is a member of the Virgo Cluster. The edge-on view of this particular galaxy, originally considered to be a barred spiral galaxy, makes it difficult to determine its true shape, but it is considered that the galaxy consists of four main components — a central bulge, a bar, a thick disc and an outer ring. The galaxy's disc is asymmetric and warped, which could be explained by NGC 4762 mergering with a smaller galaxy in the past. The remains of this former companion may then have settled within NGC 4762's disc, redistributing the gas and stars and so changing the disc's morphology.
