NGC 473 is a lenticular galaxy in the constellation of Pisces. [2] Its velocity with respect to the cosmic microwave background is 1819 ± 22 km/s, which corresponds to a Hubble distance of 87.5 ± 6.2  Mly (26.82 ± 1.91  Mpc ). [1] In addition, one non redshift measurement gives a distance of 97 Mly (29.8 Mpc). [3] It was discovered on December 20, 1786 by William Herschel. [2]

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.
