No, I used this estimate as simple way to calculate TNT equivalent. Of course energy of collision is proportional to delta-v. In solar system it’s tricky (or rather very energy-demanding) to achieve delta-v with Earth exceeding 30km/s. Which would require truly massive projectile to compare in energy with nuke.
