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

Metallic asteroids: threat or benefit?
