I was interested to learn about the mentioned 2013 meteor that resulted in injuries. Not sure how I didn't hear about that when it happened. My takeaway is that if you see something that looks like it's a bright fireball, close your eyes and turn away. And apparently move away from windows. Funny to see that the "duck and cover" exercises they do in schools are actually useful for (extremely rare) events like this. [1]

I thought we knew that despite modern criticism that duck and cover was effective for those outside of some range given a nuclear explosion?

I also think that those exercises haven't been done in schools for quite some time. I never did them despite plenty of fire and severe weather drills.

Only a small fraction of the 1.2 million are potentially concerning, most known asteroids are main belt asteroids between Mars and Jupiter and will never come dangerously close to Earth. They are all visualized here: https://eyes.nasa.gov/apps/asteroids/

Observing near earth objects (NEOs) requires shorter exposure times because their (apparent) motion is quite fast, and that has an impact on how faint the objects you can detect can be.

There are methods like synthetic tracking though, that can detect fainter objects (even those hidden in the noise, not visible by eye).

Well, at least not in one piece. Pieces of the previous one over France (which happened to be detected by the same person before it entered the atmosphere), have been found: https://karmaka.de/?p=32369

The list of successful detections BEFORE impact is indeed very short: https://en.wikipedia.org/wiki/Asteroid_impact_prediction#Lis...
