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 100,000 light years in diameter.
