An artist's illustration of the HR 6819 system. The system comprises two stars (both in blue) orbiting around a black hole (in red) (Credit: ESO/L. Calçada)

Given that each light-year — defined as the distance light travels in one Earth year — is about 6 trillion miles (9 trillion km), a black hole that lies 1,000 light-years away may not seem very close. However, to astronomers who are accustomed to cosmic distance scales, the recently-discovered HR 6819's black hole, which lies in the constellation Telescopium, is an extremely close neighbor.

        if it's right on our backyard then who knows whether if we are getting sucked in already or not.

          If we were it would take a long time from the distance

                Do you really want to know? Because...No one knows how but Astronomers and stuff have been saying for decades and eyars that we will most likely not make it alive. Um, the planet would be destoryed but the whole thing wouldn't be sucked up.

                  earth won't get sucked up. but other planet's that are so close can get sucked up.and in the second video I saw a black hole. I saw it when it was invisible. and do you know how.i saw it's sides.
