NGC 454 is a pair ofinteracting galaxies located 150 million light years away in the constellationPhoenix.John Herschel discovered it on October 5, 1834. It was described byDreyer as "very faint, small, round, brighter middle."[2]NGC 454 consists of a largeelliptical galaxy that had been destroyed by the merging.
