On 27 December last year, astronomers using the ATLAS survey telescope in Chile discovered a small asteroid moving away from Earth. Follow-up observations have revealed that the asteroid, 2024 YR4, is on a path that might lead to a collision with our planet on 22 December 2032.
Sure. By a few minutes maybe. I won’t get into the logistics of trying to set off a controlled directional explosion on a huge rock that’s likely rotating. Keep in mind also that getting it here even a minute faster means it has to change its orbit, because Earth won’t be in the original impact zone yet.
I mean if we had explosions on the surface directly away from us, would that not speed it up?
