NGC 4451 is a spiral galaxy in the equatorial Virgo constellation. It was discovered at the Copenhagen Observatory on March 19, 1865, by Heinrich d'Arrest, who used an 11" refractor telescope. [8] The galaxy is located at a distance of 85 [4] million light years and is receding with a heliocentric radial velocity of 862 km/s. [3] It is a member of the Virgo cluster of galaxies. [6]

In March 1985, Shigo Horiguchi in Japan [9] discovered a Type II-P supernova [10] in this galaxy. Designated SN 1985G, it was positioned 2″ west and 5″ north of the galaxy center. [9] The progenitor was estimated to have a mass of 21.7+4.4
−0.5  M☉ and was 8.65+0.14
−1.34 [10] million years old.
