NGC 5605 is an intermediate spiral galaxy in the constellation of Libra. Its velocity with respect to the cosmic microwave background is 3635 ± 18 km/s, which corresponds to a Hubble distance of 174.9 ± 12.3 Mly (53.61 ± 3.76 Mpc).[1] In addition, three non redshift measurements give a distance of 194.72 ± 0.68 Mly (59.700 ± 0.208 Mpc).[2] The galaxy was discovered by German-British astronomer William Herschel on 11 May 1784.[3]
The SIMBAD database lists NGC 5605 as a Seyfert II 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.[4]
