The first mentions of a strange satellite in orbit around the Earth appeared in the fifties. It was initially believed that a secret Russian satellite had been discovered in orbit.
The case became known in the press, and the bizarre object was called the Black Knight or Black Horseman.
There was a theory that Nikola Tesla was the first to receive this signal, and this should have happened in 1899 after the creation of a high-voltage radio device, which was located in Colorado Springs.
Over the following decades, there were increasing reports of allegedly decoded transmissions from extraterrestrial satellites orbiting the Earth.
The radio signal that this probe sends has also been decoded by a radio amateur listening in space.
He claims to have recorded ejections that allegedly sent stellar coordinates, the signal was sent to the Epsilon Boötis binary star system.
It was here that the approximate age of the device was taken, since this system, if it was the source of the probe, is about 13,000 light years from Earth.

While such revelations may sound strange, the object is very real and is in official photographs provided by NASA, anyone can check what they see there.
The object was in polar orbit (ideal for mapping the Earth's surface) and was moving in the opposite direction from most of the Earth's satellites, that is, from west to east.
It is known that at one time the object was of interest to the Grumman Aircraft Corporation. Careful observations were made, but the results were classified.
No longer sure if this probe is still in space. Probably, if humanity were able to make a safe debort, it would be done, so it is not known whether this "black knight" is above our heads.
