The largest SMBH in the Milky Way's vicinity appears to be that of the galaxy M87, containing 6.4 billion solar mass. The largest SMBH in the nearby Universe yet found is that of the galaxy NGC 4889, containing 21 billion solar mass.

The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus. It makes up about 14 percent of its host galaxy's mass, compared with the 0.1 percent a normal black hole would represent, scientists said.
