Asteroid 1986 DA: Radar Evidence for a Metallic Composition. 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. So are meteorites, the stony or metallic fragments that survive after entering Earth's atmosphere. Similar to Gertsch and Gertsch , they conclude that a mining venture would currently be too risky to commercially succeed. JPL is a federally funded research and development center managed for 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. 2006 Sep 7;443(7107):56-8. doi: 10.1038/nature05073.
