The NASA spacecraft hit the moon Dimorphos, but that yanked the whole system hard enough to measure. Also, the plume was modeled in 3D, and the bigger asteroid is spitting rocks at its moon. So yeah, a lot.
A long undersurface tunnel discovered in old NASA data
Also: How many near-Earth asteroids have been visited by spacecraft?
Observations show a lot of these stars are actually zombies. Also: moving an Earth-threatening asteroid just got a bit harder
The spacecraft took some pretty cool shots of the tiny, lumpy moon
It’ll likely drop to zero, but it may be a while before we know for sure
DON’T PANIC! At the moment there’s a 99% chance it’ll miss.
That title is entirely too long but it is informative
Goodbye photos from an asteroid-bound spacecraft, plus the Sun is at its activity peak now
An expanding cloud of debris may (harmlessly!) hit us in a few years
Preventing an impact could rely on bombing it...but to deflect it, not destroy it
