NGC 4598 is a barred lenticular galaxy [3] located in the constellation Virgo. [4] NGC 4598 was discovered by astronomer William Herschel on April 15, 1784. [5] The distance to NGC 4598 has not been accurately determined; measurements vary from 64 to 102 million light-years. [3] [6] 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). [3] Also, according to SIMBAD, its distance is 63.7 Mly (19.54 Mpc). [6] NGC 4598's average distance is 84.8 Mly (26.0 Mpc). [1] NGC 4598 is usually considered to be a member of the Virgo Cluster. [7] [8] However, P. Fouqu´e et al. suggests it may be a background galaxy independent of the main cluster. [9]
