  • Learning Point
  • V616 Mon is one of the closest black holes we know about, at just over three thousand light years. It orbits a nearby orange star, and was detected in 1986.
  • Black holes are super dense and heavy stars, in fact, the core or center of the stars that survive a supernova explosion.

  • Fun Facts
  • V616 Mon is pulling gas from the nearby orange star, causing it to form an accretion disk of gas and matter in orbit around the black hole.
  • The black hole and orange star orbit each other in less than six hours.
  • This black hole is 10 times the weight of our sun, and was identified as a black hole in 1986.
  • The star system emitted a very high X-Ray burst in 1975, but it was a decade before they fully understood what it meant.
