# Are there any stellar-mass black holes near the Solar System and can you detect them by using the EHT?

There are lots of stellar-mass black holes that are much closer to the Solar System than Sgr A* in the Galactic Center. However, the size of a black hole is proportional to its mass, so these stellar-mass black holes look much smaller than the Galactic Center black hole. Even if we can detect some stellar-mass black holes with the EHT, we would not be able to resolve the emission around them on the scale of their event horizon.
