Galaxy in the constellation Libra

NGC 5597 is an intermediate spiral galaxy in the constellation of Libra. Its velocity with respect to the cosmic microwave background is 2,956±18 km/s, which corresponds to a Hubble distance of 142.2 ± 10.0 Mly (43.59 ± 3.06 Mpc).^[1] However, one non-redshift measurement gives a much closer distance estimate of 125.90 Mly (38.600 Mpc).^[2] It was discovered by German-British astronomer William Herschel on 14 May 1784.^[3][4]

NGC 5597 is a Seyfert I galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.^[5][6]

NGC 5597 and NGC 5595 are listed together as Holm 638 in Erik Holmberg’s A Study of Double and Multiple Galaxies Together with Inquiries into some General Metagalactic Problems, published in 1937.^[7] The two galaxies are also listed together as VV 446 in part II of the Atlas and Catalogue of Interacting Galaxies.^[8]

Two supernovae have been observed in NGC 5597:

• SN 1981E (Type II, mag. 17) was discovered by Marina Wischnjewsky on 29 May 1981.^[9][10]
• SN 2012es (Type IIb, mag. 16.3) was discovered by L. A. G. “Berto” Monard on 12 August 2012.^[11][12]
