| Mass | 6×10^8 M☉ |
| Notable features | Overmassive black hole |
This galaxy has a double galactic nucleus much like the Andromeda galaxy. The two nucleus have a separation of 0.15 or 12 parsecs. There is a supermassive black hole (SMBH) located inside NGC 4486b.[3][4] This black hole has a mass of 500 million solar masses making it roughly one tenth of the mass of the entire galaxy. This makes the supermassive black hole within this galaxy overmassive.[2][5]
