Using color or spectral differences obtained with optical astronomy, scientists have tentatively classified asteroids according to the compositions observed first-hand in meteorites. One of these is asteroid 1986 DA. This result supports the hypothesis that 1986 DA is a piece of NiFe metal derived from the interior of a much larger object that melted, differenti-ated, cooled, and subsequently was disrupted in a cata-strophic collision. This category may require frequent maintenance to avoid becoming too large. Asteroid 1986 DA: Radar evidence for a metallic composition. This result supports the hypothesis that 1986 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. Asteroid 1986 DA - Radar evidence for a metallic composition . Echoes from the near-Earth object 1986 DA show it to be significantly more reflective than other radar-detected asteroids.  |  Epub 2002 Apr 11. Asteroid 1986 DA has a 4.7-year orbit around the Sun that brings it nearly as far out as the orbit of Jupiter. This site needs JavaScript to work properly. 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. Estimates of its value range between $6 and $7 trillion. You would literally be trying to move a mountain of steel. Hello everyone, today I bring you an impressive video of asteroid sizes, only some of them of course. And according to Wolfram|Alpha thats $384 Billion of Gold, $4.2 Trillion of Platinum, … The asteroid 1986 DA is the first, however, for which clear and emphatic radar confirmation of a metallic composition has occurred. 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. Ostro, S. J., D. B. Campbell, J. F. Chandler, A. The new radar results also offer the prospect of a valuable mineral resource for eventual space colonists. asteroid orbits are chaotically unstable ontimescales of104to 105 1400 years. 11.

Only then was it clear that the asteroid's albedo, or reflected brightness, is extremely high, leading to the conclusion about its composition. It therefore has a mass of around 100 billion tons. Frae 200 tae 400 km. 1950 DA is ~1.1 kilometers in diameter and has a mass of 4 trillion kilograms. So are meteorites, the stony or metallic fragments that survive after entering Earth's atmosphere. The asteroid 1986 DA swings out further than Mars, which would reduce the sunlight intensity to 1/4. Ostro S B et al.

The first spacecraft will travel to, rendezvous with, orbit, and land on the metallic near-Earth asteroid 1986 DA, where it will identify concentrations of platinum group metals and test several mining and minerals processing techniques for use in future missions. This category may require frequent maintenance to avoid becoming too large. Nature. AMC interns have been looking at this asteroid to supply a wealth of platinum- group metals and extend our horizons in space exploration! That's worth another couple of … Platinum is different from gold in that the market is largely industrial. First of all, 1986 DA is apparently a metallic asteroid 3.15 km in diameter. Asteroid 1986 DA: Radar Evidence for a Metallic Composition. Using the same kg/kW as near Earth, the power plant would mass 30 GW x 3000 t/GW or 90,000 tons. 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. It is also in a highly eccentric orbit, and would require a lot of velocity change to move it to the Moon’s neighborhood. This result supports the hypothesis that 1986 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. Asteroiden har en diameter på ungefär 2 kilometer och den tillhör asteroidgruppen Amor.
