Echoes from the near-earth object 1986 DA show it to be significantly more reflective than other radar-detected asteroids. Later it was found that the near-Earth asteroid 6178 (1986 DA) had a radar albedo twice that of Psyche (Ostro et al., 1991) indicating a metallic composition. Orbiting from just beyond Earth to just inside Jupiter's orbit and back every 4.7 years, the 2-kilometer- (1.6-mile-) wide object called 1986 DA shows a radar brightness "far greater than any of the five dozen asteroids we have observed before or since," according to Dr. Steven Ostro of the NASA's Jet Propulsion Laboratory (JPL), leader of the team.

Similar to Gertsch and Gertsch , they conclude that a mining venture would currently be too risky to commercially succeed. Only then was it clear that the asteroid's albedo, or reflected brightness, is extremely high, leading to the conclusion about its composition. 12. Although they observed the asteroid in 1986 soon after its discovery, the scientists needed almost 5 years to analyze the data and "build up a statistical population of observed asteroids," Dr. Ostro said. 2002 Apr 5;296(5565):132-6. doi: 10.1126/science.1068191.

And there are millions of asteroids out there!  |  Earth-approaching asteroids, like this one, and Earth-crossing asteroids, whose orbits pass within Earth's orbit, are believed to have come originally from the main Asteroid Belt between Mars and Jupiter. Eleven thousand billion dollars over 25 years is $440 B per year. It’s estimated value is around $7 trillion!! The power output would swing over the same range. Observations, Meteorites, and Models: A Preflight Assessment of the Composition and Formation of (16) Psyche. This result supports the hypothesis that I986 DA is a piece of NiFe metal derived from the interior of a much larger object that melted, differentiated, cooled, and subsequently was disrupted in a catastrophic collision. NLM It is also in a highly eccentric orbit, and would require a lot of velocity change to move it to the Moon’s neighborhood. So are meteorites, the stony or metallic fragments that survive after entering Earth's atmosphere.
