The words “Black Knight” may not ring many bells in the field of science to a simple person with little access to forbidden knowledge. In our case, it is no literature reference, nor Monty Python’s famous Holy Grail quest.

This object of worldwide interest has quite a history of interacting with a few of our most brilliant minds in the realm of science, thus making its existence undeniable among our list of unexplained UFO phenomena.

The Black Knight is a celestial body which is theorized to have roamed our orbits for more than 13,000 years, and counting. Though it is an ancient neighbor of our beloved blue star, its presence had been noticed in 1899, when Nikola Tesla was experimenting with a high-voltage radio device in Colorado Springs, and intercepted radio signals from space, which he immediately interpreted as “from another world”. His conclusions were based upon the irregular and unusual signals read by his receiver.

Nikola Tesla may have been the first but not the only one to read these enigmatic radio transmissions. Guglielmo Marconi, an Italian inventor and electrical engineer renowned for the Marconi’s law and the radio telegraph system, had apparently intercepted the same signals.

In 1953, four years before the launch of Sputnik I, the Black Knight satellite got originally into the attention of the Department of Defense, after it was noticed by Dr. Lincoln La Paz of the University of New Mexico. Striving to gather as much knowledge regarding the mysterious satellite, astronomer Clyde W. Tombaugh was assigned with leading a research mission.


A similar attempt was conducted by the Grumman Aircraft Corporation, the last century’s leading producer of military and civil aircraft. The initiative took place after capturing a photograph of the Black Knight, widely manifesting the Military’s interest in the unidentified flying object.

Thus, a special committee was created, whose sole purpose was the gathering of any piece of information relevant enough to clear little by little, the mystery around our distant neighbor.

After thorough calculations, it was estimated that the satellite orbited at a distance of about 400-600 miles from the surface of the earth and it weighed around 15 tons, which was another proof of its unearthly origins, because not even the Americans nor the Russians had the capability of sending such a heavy object into space.

Moreover, the satellite’s moving speed was calculated to be as twice as fast as any other satellite launched from Earth. The Black Knight’s movement unpredictability made it very hard to be seen in the sky, added up to the shroud of mystery that veiled this ancient and unique relic of the sky.

These characteristics were of great importance for it assembled an intricate puzzle that reveal a peculiar behavior of this rogue satellite, which made even more clear the fact that it did not belong to our technological state.

Because it was situated about the polar orbit, it meant again that it was not some sort of satellite placed there for espionage, since not one country was able to achieve polar orbit at that time.
