The legend of the black knight
The original version of this legend was put forward by nikola tesla. 1899, Tesla claimed to have discovered an unknown satellite through radio signals. Legend has it that he also did a series of research, but left no information.
Sixty-two years later, Jacques Valle, who works at the Paris Observatory in France, discovered an Earth satellite whose orbit is opposite to that of the Earth satellite, so he named it "Black Knight". This is the origin of the black knight's name.
Then at 198 1, an observatory in the Soviet Union proved its existence. It is very small, running along a huge elliptical orbit, very dazzling, like a metal sphere.
1June 1983 to 1 1 year1October, an infrared observation satellite launched by the United States scanned the celestial body twice in the direction of Orion, which proved that it had a stable orbit.
1988 12, Soviet scientists found a mysterious giant satellite above the earth through the ground satellite station. At first, both the United States and the Soviet Union thought that the satellite was launched by the other side, but it turned out that it was not.
What exactly is the Black Knight satellite?
1998, NASA gave photos of space debris, which is still considered as the satellite black knight of other planets. However, NASA explained that this is space debris caused by extravehicular activities.
The earth's surface is surrounded by thousands of satellites and countless space junk, which makes people suspect that it is too reluctant to become a black knight.
