NGC 4450
NGC 4450 is a spiral galaxy in the constellation Coma Berenices. ==Characteristics==
NGC 4450 is a member of the Virgo Cluster that, like Messier 90, shows smooth, nearly featureless spiral arms,〔(AN ATLAS OF THE UNIVERSE - THE VIRGO CLUSTER )〕 with few star formation regions〔 〕 and little neutral hydrogen compared to other similar spiral galaxies,〔 〕 something that justifies its classification as an anemic galaxy.〔 Measurements with the help of the Hubble Space Telescope show the center of this galaxy has a supermassive black hole〔(Swirling Gas Disk around Black Hole in Galaxy NGC 4450 )〕
