NGC 1101 is a lenticular galaxy in the Cetus constellation, [1] [2] and is an estimated 331 million light-years away from Earth. It was discovered on 22 November 1876 by French astronomer Edouard Stephan, who described it as "very faint, small, round with a brighter middle". [3]

Contents

NGC 1101 contains a flat-spectrum radio source [4] and it has a HI line width. [5]

To date, a non-redshift measurement gives the galaxy a distance of 81,700 megaparsecs (Mpc) or equal to ~266 million light-years. [6] This value is just outside the Hubble distance values. According to NASA/IPAC database, the diameter of NGC 1101 is calculated to be around 41.3 kiloparsecs (~135,000 light-years) if the Hubble distance were to calculate it.

NGC 485, also commonly referred to as PGC 4921 or GC 270, is a spiral galaxy in the constellation Pisces. It is located approximately 86 million light-years from Earth and was discovered on January 8, 1828 by astronomer William Herschel. It was later also observed by Heinrich d'Arrest and Herman Schultz. When NGC 485 was originally categorized in the New General Catalogue by John Louis Eil Dreyer in 1888, it was incorrectly described as a "considerably faint, pretty large, round, 8th magnitude star 3 1/2 arcmin to southwest".

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.
