What is the name of Blackhole?
The Milky Way hosts its own supermassive black hole at its center known as Sagittarius A* (pronounced “ay star”) that is more than four million times as massive as our sun. The tiniest members of the black hole family are, so far, theoretical.
Do black holes have names?
Black holes don’t have consistent naming conventions, but are often given the designation of their host galaxy. “For the case of M87*, which is the designation of this black hole, a (very nice) name has been proposed, but it has not received an official IAU approval,” says Christensen.
Who named black hole?
Princeton physicist John Archibald Wheeler coined the term in the 1960s. At the time, these objects were little more than theoretical talking points, and no one had discovered any evidence that they really existed.
Why do they call it a black hole?
A black hole is black because it absorbs all the light that hits it. It reflects nothing, just like a perfect black body in thermodynamics. Under quantum mechanics, black holes have a temperature and emit Hawking radiation, which makes them slowly get smaller.
Can you actually see a black hole?
Scientists can’t directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby.

There is a sphere around the black hole. A black hole is black because it absorbs all the light that hits it.
