How far is the black hole closest to the sun from us? What's your name?

The nearest black hole is about 1600 light-years away from the earth. This black hole is located in Sagittarius, and it forms a binary system with an ordinary star numbered V464 1SGR. Last September, X-rays and subatomic particles emitted by them filled the Milky Way in a short time. At that time, the speed of these particles was close to the speed of light. When the radiation intensity reached its peak, this binary system was once the strongest X-ray source observed on the earth. These rays were recorded by space probes and ground-based astronomical telescopes. Please accept my answer! ! ! ! ! ! ! ! ! ! !
