2012 DA14 has 2.5 megaton (MT) kinetic energy = 1X10^16 joules (J) = 1.3 x 10^8 kg * (1.27 x 10^4 m)^2

If it were 2X as large (diameter), so as to be football field size, it would have 10 MT energy.

About the size of the one of the larger US nuclear weapons.

I think it would be good if it hit the earth, on land somewhere without much intelligent life - Alabama? j/k - and left a warning. That we should develop an effective asteroid deflection system.
