NGC 459 is a spiral galaxy in the constellation Pisces.[5] Its velocity with respect to the cosmic microwave background is 12,394±22 km/s, which corresponds to a Hubble distance of 596.2 ± 41.7 Mly (182.80 ± 12.80 Mpc).[1] It was discovered by German-British astronomer William Herschel on 15 October 1784.[4] It was described as being extremely faint by John Dreyer in the New General Catalogue.[5]

Supernova

One supernova has been observed in NGC 459: SN 2011fv (Type II, mag. 18.2) was discovered by F. Ciabattari and E. Mazzoni, as part of the Italian Supernovae Search Project (ISSP), on 26 August 2011.[6][7]
