The nearest known black hole to Earth is called Gaia BH1, located about 1,560 light-years away

. It is part of a binary system with a Sun-like star and has a mass roughly 10 times that of the Sun

. However, recent studies suggest there could be black holes even closer, possibly around 150 light-years away, based on simulations of star clusters such as the Hyades cluster

. This is still under investigation and not yet confirmed by direct observation. In summary, the closest confirmed black hole is Gaia BH1 at approximately 1,560 light-years distance, but there is potential for closer black holes yet to be discovered
