Lots of small rocks can cause a 'heat pulse' over wide areas on atmospheric entry.

Lots of small rocks can cause a 'heat pulse' over wide areas on atmospheric entry.
- jjk166 4y agoThis refers to the collision ejecta falling back into the Earth's atmosphere after impact. Breaking up an asteroid in space would produce no such effect.
- LargoLasskhyfv 4y agoThat would depend on how large the asteroid is, and in how many pieces it would be 'disintegrated'? The collision ejecta don't do this because they are hot from the collision alone, it's their re-entry heat which produces the pulse. Now some massive swarm of space pebbles should do the same, given it's large enough? Ahw, so many shooting stars! And then you feel the heat.
