List of nearest black holes
This list contains all known black holes relatively near the Solar System (within our Milky Way galaxy). To make it easier to compare distances, our nearest star aside from the Sun – Proxima Centauri – is about 4.24 light years away and our Milky Way galaxy is 180,000 light years in diameter.
