The SMBH at the centre of the Milky Way is of 4.1 million solar mass, whereas the nearby Andromeda Galaxy contains a SMBH of 110-230 million solar mass. 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.
