NGC 4674 is an edge-on barred spiral galaxy located in the constellation of Virgo. Its velocity relative to the cosmic microwave background is 1,846 ± 44 km/s, which corresponds to a Hubble distance of 27.23 ± 2.09 Mpc (~88.8 million light-years). NGC 4674 was discovered by British astronomer John Herschel on 5 May 1836.
NGC 4674 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
Supernova
One supernova has been observed in NGC 4674: SN 1907A (type unknown, mag. 13.5) was discovered by Luyten on 9 May 1907.
