Appearance
![]() |
This is an incomplete list of black holes (and stars considered probable candidates) organized by size (including black hole stars of undetermined mass); some items in this list are galaxies or star clusters that are believed to be organized around a black hole.
Supermassive black holes and candidates
- OJ 287 (this BL Lac object has the largest known supermassive black hole at its center)
- 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes)
- 3C 75
- HE0450-2958
- Hypercompact stellar system (is organized around a supermassive black hole)
- Q0906+6930 (a Blazar organized around a supermassive black hole)
- Sagittarius A*
Intermediate-mass black holes and candidates
- GCIRS 13E
- M-15 NGC 7078
- M-33 Triangulum NGC 598

- XTE J1819-254/V4641 Sgr
Black holes of undetermined mass
Micro black holes
As of July 2009, the existence of micro black holes remains solely the subject of theoretical models; research in this area with particle accelerators (such as the Large Hadron Collider) is on-going, although the artificial production of micro black holes with particle accelerators has caused some to voice concerns for safety.
