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 -Washington DC. ? j/k - and left a warning. That we should develop an effective asteroid deflection system.
