The most massive black holes
TOP 14The largest black hole in this catalogue is TON 618, at 6.6×10¹⁰ M☉. Next are NGC 1277* and M87*.
Supermassive black holes sit at the centres of galaxies and scale with them: the bigger the galaxy, the bigger the hole. The largest here are billions of times the mass of the Sun, and none of them is larger across than the orbit of Neptune.
