NGC 4451 is aspiral galaxy in theequatorialVirgoconstellation. It was discovered at theCopenhagen Observatory on March 19, 1865, byHeinrich d'Arrest, who used an 11"refractor telescope.[8] The galaxy is located at a distance of 85[4] millionlight years and is receding with a heliocentricradial velocity of 862 km/s.[3] It is a member of theVirgo Cluster of galaxies.[6]
In March 1985, Shigo Horiguchi in Japan[9] discovered aType II-P supernova[10] in this galaxy. DesignatedSN 1985G, it was positioned2″ west and5″ north of the galaxy center.[9] The progenitor was estimated to have a mass of21.7+4.4
−0.5 M☉ and was8.65+0.14
−1.34[10] million years old.
