NGC 297 is an elliptical galaxy in the constellation Cetus. It was discovered on September 27, 1864, by Albert Marth [2] and is classified as type E3, based on galaxy morphological classification. [3]
To date, according to redshift measurements, a current distance of 236 Mpc (~770 Mly) is given for NGC 297. This value falls within the range of Hubble distance values. [4]
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 merging 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.
NGC 274 is a lenticular galaxy in the constellation Cetus. It is a pair of galaxies, the other being NGC 275, which it is currently interacting with. It was discovered on September 10, 1785 by William Herschel. It is roughly 120 million light-years away.
NGC 521, also occasionally referred to as PGC 5190 or UGC 962, is a barred spiral galaxy located approximately 224 million light-years from the Solar System in the constellation Cetus. It was discovered on 8 October 1785 by astronomer William Herschel.
NGC 4598 is a barred lenticular galaxy located in the constellation Virgo. NGC 4598 was discovered by astronomer William Herschel on April 15, 1784. The distance to NGC 4598 has not been accurately determined; measurements vary from 64 to 102 million light-years. According to the NASA/IPAC Extragalactic Database, its redshift based distance is 102 Mly (31.3 Mpc) while its redshift independent based distance is 88.71 Mly (27.200 Mpc). Also, according to SIMBAD, its distance is 63.7 Mly (19.54 Mpc). NGC 4598's average distance is 84.8 Mly (26.0 Mpc). NGC 4598 is usually considered to be a member of the Virgo Cluster. However, P. Fouqu´e et al. suggests it may be a background galaxy independent of the main cluster.
NGC 918 is a barred spiral galaxy in the constellation Aries, about 67 million light years from the Milky Way. It was discovered by John Herschel on Jan 11, 1831.
NGC 7329 is a large barred spiral galaxy located in the constellation Tucana. NGC 7329 was discovered by British astronomer John Herschel in 1835.
NGC 1009 is a large spiral galaxy in the constellation Cetus. Its speed relative to the cosmic microwave background is 5,594 ± 24 km/s, which corresponds to a Hubble distance of 82.5 ± 5.8 Mpc. NGC 1009 was discovered by American astronomer Edward Swift in 1886. The luminosity class of NGC 1009 is II and it has a broad HI line. To date, five non-redshift measurements yield a distance of 91.940 ± 3.045 Mpc, which is just outside the distance values of Hubble.
NGC 3751 is a type E-S0 lenticular galaxy located in the Leo constellation. It is located 450 million light-years away from the Solar System and was discovered by Ralph Copeland on April 5, 1874.
NGC 6365 is a pair of spiral galaxies in the constellation Draco. It consists of two galaxies, PGC 60174 to the south, and PGC 60171 to the north. These two galaxies are also designated respectively by the NASA/IPAC database as NGC 6365A and NGC 6365B. This pair of galaxies was discovered by German astronomer Lewis Swift in 1884.
