Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
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.
ULAS J1342+0928 is the third-most distant known quasar detected and contains the second-most distant and oldest known supermassive black hole, [1] [5] [6] [7] at a reported redshift of z = 7.54. The ULAS J1342+0928 quasar is located in the Boötes constellation . [ 3 ]
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]
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
M82 X-1 is an ultra-luminous X-ray source located in the galaxy M82.It is a candidate intermediate-mass black hole, with the exact mass estimate varying from around 100 to 1000 solar masses.
According to the data of the study, they found out the central supermassive black hole of NGC 4889 is 5,200 times more massive than the central black hole of the Milky Way, or equivalent to 2.1 × 10 10 (21 billion) solar masses (best fit of data; possible range is from 6 billion to 37 billion solar masses).

Globular cluster Mayall II (M31 G1) is a possible candidate for hosting an intermediate-mass black hole at its center [1]. An intermediate-mass black hole (IMBH) is a class of black hole with mass in the range of one hundred to one hundred thousand (10 2 –10 5) solar masses: significantly higher than stellar black holes but lower than the hundred thousand to more than one billion (10 5 –10 ...
