What is the closest black hole to Earth?

Located just under 1,600 light-years away, the discovery suggests there might be a sizable population of dormant black holes in binary systems. The black hole Gaia BH1, seen in this artist’s concept near its Sun-like companion star, is the closest black hole to Earth discovered so far.

What is the heaviest black hole?

The most massive observed black hole is TON 618, which has an estimated mass of 66 billion times the mass of the sun and is located 10.8 billion light years from Earth.

Is black hole bigger than galaxy?

And while those black holes truly are massive — weighing millions, or even billions, of solar masses — they are tiny compared with their home galaxies, reaching less than 1% of the mass of a typical galaxy and a volume a billion times smaller.
