NGC 4473 is an elliptical galaxy[2] located about 50 million light-years away[3] in the constellation of Coma Berenices.

[6] NGC 4473 is a member of a chain of galaxies called Markarian's Chain which is part of the larger Virgo Cluster of galaxies.

[3] NGC 4473 has two counter-rotating stellar discs embedded in the inner regions of the galaxy.

[3] Using the HST and spectroscopic data from the ground to measure the motions of stars in the center of the galaxy, Douglas Richstone and colleagues at the University of Michigan have concluded that NGC 4473 has a supermassive black hole[10] with an estimated mass of roughly 100 million solar masses (1×108 M☉).

[11][12] Its diameter is estimated to be around 4.459 astronomical units (415 million mi).
