The Black Knight, 13 000 year-old Alien Satellite Orbiting Earth

Extraterrestrial satellite has been orbiting Earth for quiet some time now. Most talked about object since late 50s who caused big interests in media. At first they thought it was Russian satellite.
Nikola Tesla was the first one who picked up radio signal in 1899 and he believed its coming from space which he said in the public conference.
In 1920, amateur radio HAM operators received same signal.
Later by 1960 USA and Russians was both sending satellites in space. On February 11, 1960 US Navy picked up something what was described as dark, tumbling object which wasnt their nor Russian. Is it really Alien artifact or satellite?
