Black holes can theoretically exist at microscopic scales, with Earth compressed into a black hole being only the size of a small marble, though the smallest black hole ever discovered is much larger, located in the constellation Monoceros with a mass three times that of the Sun and an event horizon of approximately 9 kilometers.

HOW SMALL CAN A BLACK HOLE REALLY GET #shortsAdded:
Black holes so tiny that they could be smaller than an atom exist [music] in the universe, but the scariest part is that their mass would still be comparable to that of enormous mountains. We're used to thinking of black [music] holes as giants devouring stars and entire galaxies, but physics allows for the existence of almost microscopic black holes. If Earth were suddenly [music] transformed into one of these, our planet would be compressed to the size of a small marble. Such objects are virtually impossible to detect with modern telescopes. So, the smallest black [music] hole discovered is still much larger. It's located in the constellation Monoceros, has a mass just three [music] times that of the Sun, and its event horizon, the region from which not even light can escape, is only about 9 km.
