    the likely mass of 2012 DA14 - assuming similar (chondritic) composition. Even using the current larger estimate of physical size.

    If 2012 DA14 were largely metallic the mass differential for the russian impact would be much larger, perhaps up to 1/100th. (Assuming largely nickel composition).
