ASTRONOMERS DISCOVER THE NEAREST BLACK HOLE KNOWN TO THE EARTH

Discovered using the Gemini North telescope and Gaia telescope in Hawaii, this black hole has been found to be about 5 to 100 times the mass of the Sun and 10 times larger than the Sun. This black hole, called Gaia BH1, is located in the constellation Ophiuchus and is located approximately 1600 light-years from Earth.

So How Close Exactly?

The average of 1 light-year is 9.5 kilometers. 1600 light-years is 9.5 km x 1600 light-years, that is, approximately 1.52e+16 km. To understand this better, when we divide this distance by the Earth-Sun distance, that is, 1 astronomical unit, we get approximately 101333333 EU units. This means that it is 101333333 times farther from us than the Earth-Sun distance. Don't be afraid, there is no need for Yani, the universe is very, very big.

The closest known black hole before this movement was at a distance of about 3 times this distance from our movements just before.

So How Was It Discovered?

While astronomers were examining data from the Gemini North telescope, their strange appearance in orbit of a star was different. The team of these regulators did a more detailed analysis using other observation observations collected for the same system. As a result of these ratios, it was determined that this system could potentially be a black hole.
