They initially tracked the black hole's two companion stars using the 2.2-metre telescope at ESOâs La Silla Observatory in Chile. Calçada Astronomers find closest black hole to Earth, hiding in plain sight Neutron Star Supernova Black Hole Yellow Dwarf. In fact, the ESO team thinks HR 6819 could help reveal the true nature of LB-1, which may also be a triple system, said co-author Marianne Heida, a postdoctoral fellow at ESO, in a statement. The system is close enough to Earth that the stars near the black hole can be seen with the naked eye. Two bright stars orbit an unseen black hole in this artist's impression of the HR 6819 triple system. Rivinius and his collaborators estimated that the black hole in HR 6819 was about 1,000 light-years from Earth, making it the closest known black hole. Enlarge / Artistâs impression showing orbits of the objects in the HR 6819 triple system. Recently discovered HR 6819 is the closest-known of what celestial phenomenon/object to Earth? However, Hugues Sana (KU â¦ Its â¦ If real, HR 6819âs black hole would take first place as the closest black hole to Earth, knocking from the pedestal the accreting black hole in V616 Monocerotis, which lies about 3,300 light-years away based on Gaia measurements. An interesting bit of recent astronomy news is the possible discovery of a black hole in a nearby star system, HR 6819. The black hole in HR 6819 in the constellation Telescopium can't be seen, but the two visible stars can be spotted with the naked eye from Earth. Question: Recently discovered HR 6819 is the closest-known of what celestial phenomenon/object to Earth? On a human scale, a thousand light-years is an immense distance. ESO/L. If a model of the Milky Way were scaled so that Earth and the sun were only a hairâs width apart, HR 6819 â¦ About 1,000 light-years from Earth, astronomers have discovered the closest black hole in a system called HR 6819. 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. It is about three times closer than the nearest known black hole - V616 Monocerotis. The black hole in question is 1,000 light-years from Earth in the Telescopium constellation and forms part of a triple system, called HR 6819, which is how the ESO stargazers managed to find it in the first place. ESO/Digitized Sky Survey 2. Given that each light-year â defined as the distance light travels in one Earth year â is about 6 trillion miles (9 trillion km), a black hole that lies 1,000 light-years away may not seem very close. Answer: The correct answer is Black Hole.
