sorae – Discovery of “Gaia BH1”, the closest black hole to Earth in history

This was introduced by sorae in an article on November 17, 2022.Black hole “Gaia BH1” and star “Gaia DR3 4373465352415301632”” This is an imaginary drawing.

Gaia DR3 4373465352415301632” is a star in the celestial catalog observed by the astronomical positioning satellite “Gaia”. It is only 1,560 light-years away from Earth, and Gaia’s observations have revealed that its position is slightly shifted, and its name has been proposed for some time as a candidate for a binary star system with an “invisible companion star.” . At the time (2022), researchers reported through precise observations of Gaia DR3 4373465352415301632 using the Gemini North Telescope that this companion star could not be explained by anything other than a black hole.

The original article explains the nature of the companion star, named “Gaia BH1,” and why it cannot be explained by anything other than a black hole.

* “Gaia BH1” beats the previous shortest distance record of “A0620-00 (Monocerina X-1)” by approximately 3,000 light years, and may be the closest black hole to Earth.
