The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
OJ 287 core black holes — a BL Lac object with a candidate binary supermassive black hole core system [23] PG 1302-102 – the first binary-cored quasar — a pair of supermassive black holes at the core of this quasar [24] [25] SDSS J120136.02+300305.5 core black holes — a pair of supermassive black holes at the centre of this galaxy [26]
Micro black holes, also called mini black holes or quantum mechanical black holes, are hypothetical tiny (<1 M ☉) black holes, for which quantum mechanical effects play an important role. [1] The concept that black holes may exist that are smaller than stellar mass was introduced in 1971 by Stephen Hawking .
The science and philosophy channel Kurzgesagt has come out with a mind-blowing size comparison of the universe's black holes. The post Black Hole Size Comparison Chart Gives New View of Universe ...

Black holes are some of the most violent objects in the universe. And the bigger they get, the more powerful they are. Here's how big they really are.
Below there is a list of the least massive known black holes, sorted by increasing mass. The unit of measurement is the solar mass , equivalent to 2.0 × 10 30 kg. List
IGR J17091 is a stellar mass black hole with a mass between 3 and 10 M ☉. It is a binary system in which a star orbits the black hole. [4] Its small size may make it a candidate for the smallest black hole discovered. [5] However, as of 2017 its mass was described as "unknown". [6]
