context_page_description: NGC 4457 is a spiral galaxy located about 55 million light-years away in the constellation of Virgo. It is also classified as a LINER galaxy, a class of active galaxy defined by their spectral line emissions. NGC 4457 Is inclined by about 33°. It was discovered by astronomer William Herschel on February 23, 1784. Despite being listed in the Virgo Cluster Catalog as VCC 1145, NGC 4457 is a member of the Virgo II Groups which form an extension of the Virgo cluster.
  NGC 4457 may have had a recent minor merger with another galaxy.
  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.
