A meteor that survives the fiery descent through Earth’s atmosphere is known as a meteorite. This work is part of the Planetary Astronomy Program of NASA's Office of Space Science and Applications, with additional support by the National Science Foundation. 1986 DA may be a relic of a larger body which came together, melted, separated into layers of heavy metal and light rock, cooled, and then was smashed into fragments in a catastrophic collision with another large asteroid. Asteroid 1986 DA is a metallic asteroid made up of iron, nickel, gold, and platinum. This 2-kilometer asteroid, which appears smooth at centimeter to meter scales but extremely irregular at 10- to 100-meter scales, might be (or have been a part of the parent body of some iron meteorites. 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. 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). Pages in this category should be moved to subcategories where applicable. Another mile-wide Near-Earth Asteroid, known as 1986 DA, is said to contain 100,000 tonnes of platinum and 10,000 tonnes of gold. Abstract. Ostro S B et al. Ostro, S. J., D. B. Campbell, J. F. Chandler, A. Echoes from the near-Earth object 1986 DA show it to be significantly more reflective than other radar-detect-ed asteroids.

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. (1991), “Asteroid 1986 DA: Radar Evidence for a Metallic Composition”, Science 252 June 7 1991. Could 1986 DA be the target asteroid for 2027? Radar observations of the near-Earth asteroid 1986 DA were carried out at the Arecibo Observatory in April 1986, two months after its discovery. This result supports the hypothesis that 1986 DA is a piece of NiFe … The asteroid 1986 DA is the first, however, for which clear and emphatic radar confirmation of a metallic composition has occurred. Hello everyone, today I bring you an impressive video of asteroid sizes, only some of them of course. The asteroid 1986 DA swings out further than Mars, which would reduce the sunlight intensity to 1/4. NLM Only then was it clear that the asteroid's albedo, or reflected brightness, is extremely high, leading to the conclusion about its composition. The radar albedo of the largest M class asteroid 16 Psyche was consistent with nearly pure metallic composition if its surface porosity was similar to that of the Moon (Ostro et al., 1985). Using color or spectral differences obtained with optical astronomy, scientists have tentatively classified asteroids according to the compositions observed first-hand in meteorites. ThebandwidthBofan asteroid's The 1986 DA and 1986 EB: M-class asteroids in near-Earth orbits. 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. It is also in a highly eccentric orbit, and would require a lot of velocity change to move it to the Moon’s neighborhood. 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. Virtually all of the mass could come from the asteroid. Object Epoch (UT) Measurement Sigma Units freq rcvr xmit bp ref Observer(s) Notes Modified 4.
