Els mesuraments del radar suggereixen que és compost de … Overlongertimescales, 1986DA'sorbitmightintersect the orbit of Earth as a consequence of secular perturbations by the planets, and for this reason 1986 DAis referred to as an Earth-crossing asteroid (17). A. Hine, R. S. Hudson, K. D. Rosema, and I. I. Shapiro. You would literally be trying to move a mountain of steel. A. Hine, D. B. Campbell, K. D. Rosema, R. S. Hudson and S. J. Ostro. Radar results are consistent with the hypothesis that 1986 HA is a piece of NiFe metal derived from the interior of a much larger object that melted, differentiated, cooled and subsequently … And according to Wolfram|Alpha thats $384 Billion of Gold, $4.2 Trillion of Platinum, $269 Billion of Iron and $20 Trillion of Nickel. Increasing the supply would drive down the price but probably not as much as gold.) JPL is a federally funded research and development center managed for Nature. (The Wikipedia article on the asteroid 1986 DA estimates it is worth $11 T, mostly from high platinum prices. A meteor that survives the fiery descent through Earth’s atmosphere is known as a meteorite. First of all, 1986 DA is apparently a metallic asteroid 3.15 km in diameter. Asteroid 1986 DA: Radar evidence for a metallic composition Radar observations of the near-Earth asteroid 1986 DA were carried out at the Arecibo Observatory in April 1986, two months after its discovery.

Using color or spectral differences obtained with optical astronomy, scientists have tentatively classified asteroids according to the compositions observed first-hand in meteorites. Platinum is different from gold in that the market is largely industrial. Analysis of the radar echoes reveals an extremely lumpy body, possibly even multi-lobed like 1989 PB, observed and imaged by Ostro and colleagues almost two years ago.
