Yep, and I see they put a the size of the comet way, way larger than my measly 2km. If it is that big and it hits anything I'd imagine that would be pretty spectacular. Still, there is an awful lot of empty space within the current error margin. Hopes are not very high yet. Imagine the research you could do examining the results of such an impact.

Elenin said that since C/2013 A1 is a hyperbolic comet and moves in a retrograde orbit, its velocity with respect to the planet will be very high, approximately 56 km/s. “With the current estimate of the absolute magnitude of the nucleus M2 = 10.3, which might indicate the diameter up to 50 km, the energy of impact might reach the equivalent of staggering 2ื10นบ megatons!”
