The best modern comparison is the 1908 Tunguska Event, when an asteroid or comet fragment measuring 30-50 meters exploded over Siberia, flattening 80 million trees across 770 square miles.

That's the same size of asteroid that exploded over Siberia in 1908 injuring people and damaging buildings over 200 square miles. The most serious near-miss, and the closest comparison with YR4, was ...
