>>11613350>big single mass impact vs space sand impactI'm not sure which would be worse. Probably the space sand. That much material hitting the atmosphere will super heat the air and can bake everything to about 2-3 inches into the soil. Though, a similar thing happens when a big single mass impact occurs and splashes debris into the atmosphere. Though, in the latter scenario there will be less debris than the space sand and the impact will be in one location. Yet, there will be seismic activity with the large impact and its debris reentry will splash across the atmosphere all over the world, where the space sand would only hit one side of the planet.
So, I think not shooting the asteroid would be a bad thing over all.
