NGC 4450 imaged by the Hubble Space Telescope

NGC 4450 is a spiral galaxy in the constellation of Coma Berenices. It has an apparent visual magnitude of 10.1 and spans an angular size of 5.4′ × 4.1′.

Characteristics

NGC 4450 is a member of the Virgo Cluster that, like Messier 90, shows smooth, nearly featureless spiral arms, 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.
