NGC 4453
Galaxy in the constellation Virgo
From Wikipedia, the free encyclopedia
NGC 4453 is a peculiar spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 12,051±24 km/s, which corresponds to a Hubble distance of 579.7 ± 40.6 Mly (177.74 ± 12.45 Mpc).[1] It was discovered by German-British astronomer William Herschel on 28 January 1784.[2][3]

NGC 4453 is listed as VCC 1130 which would make it part of the Virgo cluster. However, its distance (~178 Mpc) is about 10 times farther than the distance to the cluster (~16.5 Mpc), making the galaxy too far away to be a part of it.
Supernova
One supernova has been observed in NGC 4453:
- SN 1966F (type unknown, mag. 17.5) was discovered by Polish astronomer Konrad Rudnicki on 18 July 1966.[4][5]
