In 1999 a violent outburst at V4641 Sgr revealed it to be the closest known black hole to Earth. Originally thought to be positioned approximately 1,600 light-years from Earth, later observations showed it to be at least 15 times farther away.
Its radius in 25 km
mass is nearly 10 times that of the sun
