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.
