The Cygnus X-1 Black Hole is a black hole system that is one of the strongest X-ray sources seen from Earth in the constellation Cygnus discovered in 1964 and was the subject of physicists Stephen Hawking and Kip Thorne.
It's age is approximately 5 million years old with a with a radial velocity of -13km/s and a right ascension of 19h 58m 21.67595s. It's mass is 14-16 and a radius of 20-22.It was discovered during a 1964 rocket flight.
The largest star in the Cygnus OB3 association has a mass 40 times that of the Sun. The Cygnus X-1 system shares a common motion through space with an association of massive stars named Cygnus OB3, located at approximately 2,000 parsecs from the Sun.Like all black holes, it is invisible and it's job in space is to suck in dead stars. In Star Trek, it is used by villains to destroy a planet they don't want.
It's variable type is ellipsoidal variable, also known as variable star.There is two types of variable star:
- Intrinsic variables, whose luminosity changes
- Extinsic variables, whose apparent changes in brightness are due to changes in the amount of their light that can reach Earth.
