The famously first-observed black hole in Cygnus known as Cygnus X-1 is about 6,070 light years distant.
No, we have not seen any evidence of a black hole in our solar system.
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.
The supermassive black hole in the center of our Milky Way is at a distance of about 28,000 light-years. The nearest known stellar black hole is at a distance of about 3000 light-years.
It is actually difficult to determine the distance to black holes, but a nearby object believed to be a black hole from observations of strong X-ray emission is Cygnus X-1, located about 8000 light years away. Cyg X-1 is an ordinary star that is believed to be orbiting a black hole.
"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.
The only "named" black hole is called "Cygnus X-1", for the first X-ray source in the constellation Cygnus.
No. The nearest black hole is about 1,600 light years away.
It seems that the closest known black hole is at a distance of about 3000 light-years.
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 black hole candidate to be discovered is Cygnus X-1, which was identified in 1964. It is located in the constellation Cygnus and is one of the most studied black hole candidates due to its strong X-ray emissions.
The average travel distance from a black hole on Earth would depend on the distance to the nearest known black hole, which is typically thousands to millions of light years away. Traveling to a black hole would require advanced technology and is not currently feasible with our current understanding of physics.
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.
