Scientists have discovered what may be called the smallest-known black hole in the Milky Way galaxy and the closest to our solar system - an object so curious that they nicknamed it 'the Unicorn.
As per researchers this black hole is roughly three times the mass of our sun, testing the lower limits of size for these extraordinarily dense objects that possess gravitational pull so strong not even light can escape. A luminous star called red giant orbits with the black hole in a so-called binary star system named V723 Mon.
The black hole in located about 1,500 light years from earth. While it may be tha closest one to us. Black holes like this one form when massive stars die and their cores collapse.
There are three categories of black holes. The smallest, like 'the Unicorn,' are so-called stellar mass black holes formed by the gravitational collapse of a single star. There are gargantuan black holes and a few intermediate-mass black holes.
