NGC 4457 is an intermediate spiral galaxy located about 55 million light-years away[2] in the constellation of Virgo.[3] It is also classified as a LINER galaxy, a class of active galaxy defined by their spectral line emissions.[4][2] NGC 4457 Is inclined by about 33°.[5] It was discovered by astronomer William Herschel on February 23, 1784.[6] Despite being listed in the Virgo Cluster Catalog as VCC 1145,[7] NGC 4457 is a member of the Virgo II Groups[8][9][10] which form an extension of the Virgo cluster.[8][11]
NGC 4457 may have had a recent minor merger with another galaxy.[12]
On July 1 2020, an astronomical transient was discovered in NGC 4457 by astronomer Kiochi Itagaki and confirmed by ASAS-SN. Spectroscopic classification determined the object to be a Type Ia Supernova, SN 2020nvb.[13]
