50m is not much but still enough to pack a hell of a wallop. i've actually stood on the rim of the Barringer Crater in AZ. it was made by an asteroid only 50m in diameter going about 13km/s. it left a crater that is 1,200m wide and about 170m deep. nothing that would have "global" implications but it would make an immense mess of a city.

... and similar to what is presumed to have caused the Tunguska event in 1908 I believe...

As for 2012DA14, going to be fascinating to see what Earth bound optics can see of it. I doubt much detail...
