NGC 5674
Galaxy in the constellation Virgo
From Wikipedia, the free encyclopedia
NGC 5674 is an intermediate spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 7,703±18 km/s, which corresponds to a Hubble distance of 370.6 ± 26.0 Mly (113.62 ± 7.96 Mpc).[1] However, three non-redshift measurements give a much closer mean distance of 240.70 ± 4.90 Mly (73.800 ± 1.501 Mpc).[2] It was discovered by German-British astronomer William Herschel on 12 May 1793.[3][4]

NGC 5674 is 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.[5][6]
According to Abraham Mahtessian, NGC 5674 and NGC 5652 form a pair of galaxies.[7]
Supernova
One supernova has been observed in NGC 5674:
- SN 2025ajnc (Type Ia, mag. 19.4685) was discovered by the Zwicky Transient Facility on 28 December 2025.[8]
