NGC 4734 is a spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 7835 ± 23 km/s, which corresponds to a Hubble distance of 115.56 ± 8.10 Mpc (∼377 million light-years).[1] It was discovered by British astronomer John Herschel on 7 April 1828.[2]

The SIMBAD database lists NGC 4734 as a LINER-type active galaxy nucleus, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[3]

One supernova has been observed in NGC 4734: SN 2024gvc (type Ic, mag 19.7178) was discovered by the Zwicky Transient Facility on 17 April 2024.[4]
