Although predicted theoretically long before, credit for discovery of the first strong black hole candidate through astronomical observation in the x-ray binary system of Cygnus X-1 goes to Bolton, Murdin, and Webster in 1972.
Cygnus X-1 was identified as the first black hole by astronomers Tom Bolton and Louise Webster in 1971. They observed the star in the Cygnus constellation exhibiting characteristics consistent with a binary star system with a massive unseen companion, leading to the identification of Cygnus X-1 as a black hole.
It is believed that there is a black hole in the constellation of Cygnus (the Swan), the strong X ray source Cygnus X-1 is believed to be a binary system where one component is a black hole. (see the link Below).There is also a super-massive black hole in the center of our galaxy (the Milky Way) this is to be found in the constellation of Sagittarius and is called Sagittarius A*. (see the link below).
The first strong black hole candidate to be generally accepted from observational evidence back in 1972 was the Cygnus X-1 x-ray binary.
One that is fairly famous is Sagittarius A* - the supermassive black hole at the center of our Milky Way, about 26,000 light-years from here, and with a mass of about 4 million solar masses. For additional black holes, check the Wikipedia article "List of black holes".
The first strong black hole candidate observed was in an x-ray binary system in constellation Cygnus and is called Cygnus X-1 (so named because it was a strong x-ray source). Observational evidence continues to support the notion that it could only be a black hole; its mass is estimated at a little under 15 times the mass of our sun, with a Schwarzschild radius of about 44 km.
There is no black hole in our solar system. The closest known black hole is a pair of them in the Cygnus constellation, about 1,000 light years away from Earth.
The famously first-observed black hole in Cygnus known as Cygnus X-1 is about 6,070 light years distant.
The only "named" black hole is called "Cygnus X-1", for the first X-ray source in the constellation Cygnus.

"Cygnus" is the latin word for "swan." It is the name given to a constellation in our skies. Within this constellation is a major source of x-rays; the source of which was eventually regarded as a black hole. This was the first object that most astronomers concluded was unambiguously a black hole, a conclusion reached about thirty years ago.
Cygnus X-1, as far as we know, is a black hole; it therefore does not have a size. However, as with all black holes, it does have an event horizon and this radius is estimated to be around 26km.
There is a supermassive black hole at the center of our galaxy, and perhaps most other galaxies. Additionally, there are several smaller black holes relatively near by, as cosmic distances go. The first black hole ever detected is in the constellation Cygnus, called "Cygnus X-1".
Yes. Matter falls into black holes all the time; the first known black hole was the "Cygnus X1" black hole, which was discovered by the X-ray emissions caused by matter being pulled off the companion star and falling into the black hole.

Observational confirmation of the Cygnus X-1 binary, suspected since about 1971 of being a black hole, came from a space and land-based radio and x-ray instruments in 1972, and was widely accepted as a black hole by 1973.
The concept of black holes was first proposed by physicist John Michell in 1783, but the actual discovery of a black hole took several decades. In the 20th century, scientists like Karl Schwarzschild and Subrahmanyan Chandrasekhar made significant advances in understanding the theoretical aspects of black holes. However, the first observational evidence for a black hole came in 1971 with the discovery of a strong radio source known as Cygnus X-1. Further observations and studies confirmed that Cygnus X-1 was a binary system consisting of a black hole and a companion star.
