    Answer:
It is actually difficult to determine the distance to black holes, but a nearby object believed to be a black hole from observations of strong X-ray emission is Cygnus X-1, located about 8000 light years away. Cyg X-1 is an ordinary star that is believed to be orbiting a black hole. There are other nearby candidates for black holes which include :

GRO J0422+32 =V518 Per 1.39 kpc or 2 kpc
A0620-00 = V616 Mon 0.87 kpc or 1.05 kpc
XTE J1118+480 0.83 kpc or 1.8 kpc

(kpc stands for kiloparsec, or approximately 3250 light years)
