It was considered a real threat for a number of years with an estimated size of 130 meters and a rating of 1 on the 10-point Torino Impact Hazard Scale.

Space Weathering on Asteroids as Reason for their Disintegration

All surfaces of rocky bodies in our planetary system are exposed to a certain bombardment of (tiny) bits of rocks, so-called meteorites. Most ejecta out of these impacts are falling back to the lunar surface to build a layer of dust with time called regolith. Since that we have seen the nice footprints of astronauts in the lunar dust as proof: The Moon`s gravity

Thanks to the new infrared method will be possible to identify many other metal-rich asteroids. What surprised the scientists was that metallic asteroids emit less

: Plot of the orbits of all presently known Potentially Hazardous Asteroids (PHAs)

Figure 1: Plot of the orbits of all presently known Potentially Hazardous Asteroids (PHAs), i.e. over 1400 as of early 2013. PHAs are asteroids with a size of at least 140 m and with orbits passing the Earth orbit within 7.5 million kilometres. The Earth orbit
