This is a list of black holes (and stars considered probable candidates) organized by size (including black holes of undetermined mass); some items in this list are galaxies or star clusters that are believed to be organized around a black hole. Messier and New General Catalogue designations are given where possible.

Supermassive black holes and candidates[edit]


Intermediate-mass black holes and candidates[edit]

Stellar black holes and candidates[edit]

Multiple black hole systems[edit]

Binary black holes[edit]

  • SDSS J120136.02+300305.5 core black holes — a pair of supermassive blackholes at the centre of this galaxy[7]
  • PG 1302-102 – the first binary-cored quasar — a pair of supermassive blackholes at the core of this quasar[8][9]

Trinary black holes[edit]

As of 2014, there are 5 triple black hole systems known.[10]
