A small asteroid burned up in Earth's atmosphere off the coast of California just hours after being discovered and before impact monitoring systems had registered its trajectory.

What is the sense of having a impact monitoring system if it doesn't work properly? Okay this small one slipped by, but what if the next one is 100 meters acr oss and it slips by? I kinda know what will happen, im just saying.

Hoping this system does better with bigger "asteroids". Those 1 meter in diameter don't seem to be a threat. And, of course, there a many many more the size of grains of sand that hit Earth every day.

So, how are we doing detecting things big enough to cause real damage on Earth's surface? Things like the one that blew up over Chelyabinsk? That one was estimated to be about 18 meters in diameter. It came at us from a direction that was close to the Sun from our perspective, and was not detected, either. ( See https://en.wikipedia.org/wiki/Chelyabinsk_meteor)
