What the simulator shows

NASA puts the impact energy at 0.17 kilotons of TNT. A stony body about 1.9 m across at 11.5 km/s carries that energy, and that is the scenario the simulator loads. The object exploded 35.0 km above the surface. No town lies within 150 km of the point.

This is a simplified model, not a damage report. Real effects depend on soil, buildings, terrain and the details of the event.
