Astronomers discover black hole closer to Earth than any before

  • The black hole is tiny, only 40km in diameter
  • It is not close enough to swallow anything, but it is warping the orbit of its nearest star
  • Scientists estimate the black hole was violently born from a supernova 15 million years ago
  • The new black hole is part of what used to be a three-star dance in a system called HR6819.
  • The star QV Tel is magnitude 5.37 and 1120 light years away
  • Studies using the 2.2m telescope at La Silla Observatory in Chile reveal the inner of the two visible stars to be orbiting an unseen object every 40 days.
  • Presumed to be a black hole, this object has a likely mass of at least four times that or our Sun.
